“…CeRhSb shows a large peak in TEP at 20 K, signaling the onset of Kondo insulator state [589]. TEP in CePdSn shows a broad peak at 110 K and a deep narrow peak at 22 K, which is similar to heavy fermion Ce compound with antiferromagnetic ordering [364]. TEP shows a weak peak around 20 K for other RPdSn (R=Pr, Nd, Sm, GdHo) compounds, which is attributed to the phonon drag [364].…”

“…At higher temperatures, the slope of the curve is slightly negative for light rare earth compounds, while slightly positive for heavy rare earth compounds. This difference as well as in resistivity in these compounds hints at the difference in band structures of these two groups [364]. TEP measurements were performed for CeTGe (T=Ni, Pd, and Pt) down to 0.1 K. The TEP shows single and positive peak for CeNiGe and second positive peak was observed in CePdGe and CePtGe [590].…”

“…The peak corresponding to the AFM transition gets broadened with increase in pressure and disappears at a pressure higher than 60 kbar, which indicates that the pressure transformed the magnetic state into a non magnetic state [474]. In SmPdSn and DyPdSn, the resistivity shows two bends; first is due to the onset of AFM ordering and second may correspond to change in magnetic structure [364].…”

RTX (R=rare earths, T= 3d/4d/5d, transition metals such as Sc, Ti, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag, Os, Ir, Pt, Au, and X=p-block elements such as Al, Ga, In, Si, Ge, Sn, As, Sb, Bi) series is a huge family of intermetallics compounds. These compounds crystallize in different crystal structures depending on the constituents. Though these compounds have been known for a long time, they came to limelight recently in view of the large magnetocaloric effect (MCE) and magnetoresistance (MR) shown by many of them. Most of these compounds crystallize in hexagonal and tetragonal crystal structures. Some of them show crystal structure modification with annealing temperature; while a few of them show iso-structural transition in the paramagnetic regime. Their magnetic ordering temperatures vary from very low temperatures to temperatures well above room temperature (~510 K). Depending on the crystal structure, they show a variety of magnetic and electrical properties.These compounds have been characterized by means of a variety of techniques/measurements such as x-ray diffraction, neutron diffraction, magnetic properties, heat capacity, magnetocaloric properties, electrical resistivity, magnetoresistance, thermoelectric power, thermal expansion, Hall effect, optical properties, XPS, Mössbauer spectroscopy, ESR, μSR, NMR, NQR etc. Some amount of work on theoretical calculations on electronic structure, crystal field interaction and exchange interactions has also been reported. The interesting aspect of this series is that they show a variety of physical properties such as Kondo effect, heavy fermion behavior, spin glass state, intermediate valence, superconductivity, multiple magnetic transitions, metamagnetism, large MCE, large positive as well as negative MR, spin orbital compensation, magnetic polaronic behavior, pseudo gap effect etc.Except Mn, no other transition metal in these compounds possesses considerable magnetic moments.Because of this RMnX compounds in general have high ordering temperatures. Interstitial modification using hydrogen and nitrogen is found to alter their crystal structures and magnetic properties considerably. RTX compounds also show interesting pressure effects on their structural and magnetic properties. In summary, these compounds show variety of physical properties over a wide range of temperatures. This review is intended to cover all the important results obtained in this family, particularly in the last few years.

“…The existence of successive magnetic transitions with temperature as well as the multistep metamagnetism under high field has been clarified for TbNiSn and TbRhGe single crystals [5][6][7][8][9][10]. For another isostructural compound TbPdSn, the results of bulk magnetic measurements on polycrystalline samples have been reported so far [11][12][13]. In this studies, we present crystal structure, specific heat and magnetic properties of TbPtSn, TbPdSn, TbNiSn compounds at low temperature.…”

Abstract:The TbTSn compounds (T = Pt, Rh) have been prepared by arc-melting in purified Ar atmosphere. Crystal structures were studied by X-ray powder diffraction. The Rietveld analysis shows the single phase in hexagonal ZrNiAl-type structure for TbPtSn and TbRhSn compounds. Magnetic properties and specific heat measured by mean of Physical Properties Measurement System (PPMS) demonstrated the phase magnetic transition at Néel temperature T N .

Dedicated to Professor Jack D. Dunitz, who thinks more deeply about structure than anyone else we know There are more than 2000 compounds with RE/M/E 1 : 1 : 1 stoichiometry, where RE is a rare earth, actinide, or from groups 1 ± 4, E is a late transition metal from groups 8 ± 12, and E belongs to groups 13 ± 15. In the first paper of a series, we describe the primary structural characteristics of this large class of compounds, focusing on the geometries and bonding in the [ME] nÀ anionic sublattices. We start with a detailed description of the EuAuSn lattice, by emphasizing its essential building blocks and the symmetry operations connecting them, in order to set up a way of describing systematically the geometric features of other RE M E frameworks. Nearly all these phases have eclipsed hexagonal layered arrangements (with only MÀE bonds within these slabs) in the ME sublattice. In most cases, stacking the puckered layers in the third dimension gives rise to MÀE, MÀM, or EÀE bonds, alternating in certain patterns. We point to several interesting sets of RE M E compounds, of like structure, but whose electron counts vary significantly. The structures of nonlayered networks and their mostcommon electron counts are also introduced.Enumeration. ± In this work, we begin to look at bonding patterns in a large group of ternary compounds with the RE/M/E 1 : 1 : 1 stoichiometry, where RE rare earth (lanthanide (Ln) or actinide (An)), alkali, alkaline earth, or from groups 3 and 4, M late transition metal, from groups 8 ± 12, and E main group element, from groups 13 ± 15. In the periodic table in Fig. 1, we highlighted with yellow the elements we refer to as RE, M in red, and E in blue. We will call the general class the RE M E structures. In CRYSTMET (a database for inorganic compounds) [1] and ICSD (Inorganic Crystal Structure Database) [2], more than 2000 substances fall into this category.As shown in Table 1, more than 60% of compounds have a lanthanide (Ln) as countercation. This is the reason for our use of RE in the RE M E class notation, albeit many phases do not contain a lanthanide. In Tables 2 and 3 from Appendix, we list the compounds, grouping them (somewhat arbitrarily) by the space groups in which they crystallize, and give the archetypical structure types, along with simple descriptions of their structural characteristics and electron counts. We are going to refer to these tables throughout our subsequent discussion.We abbreviate orthorhombic-RE M E as o-RE M E, hexagonal-RE M E as h-RE M E, cubic-RE M E as c-RE M E, tetragonal-RE M E as t4-RE M E, trigonal-RE M E as t3-RE M E, and monoclinic-RE M E as m-RE M E.As may be seen from Table 1, there is ± to put it mildly ± a myriad of RE M E phases, covering most but not all possibilities.
