“…Geometrically frustrated lattices play host to a number of emergent quantum mechanical phases including quantum spin liquids [1], resonating valence bond states [2], and complex magnetic orders [3]. Such systems are typically electronic insulators constructed from low-connectivity lattices that enforce competing magnetic interactions and enhanced quantum mechanical fluctuations [4].…”

In the presence of a magnetic field frustrated spin systems may exhibit plateaus at fractional values of saturation magnetization. Such plateau states are stabilized by classical and quantum mechanisms including order by disorder, triplon crystallization, and various competing order effects. In the case of electrically conducting systems, free electrons represent an incisive probe for the plateau states. Here we study the electrical transport of Ising-type rare-earth tetraborides RB 4 (R = Er, Tm), a metallic Shastry-Sutherland lattice showing magnetization plateaus. We find that the longitudinal and transverse resistivities reflect scattering with both the static and the dynamic plateau structure. We model these results consistently with the expected strong uniaxial anisotropy on a quantitative level, providing a framework for the study of plateau states in metallic frustrated systems.

“…It has been reported that Ba 3 NbFe 3 Si 2 O 14 undergoes an antiferromagnetic phase transition at approximately 27 K [23]. A much larger CurieWeiss temperature of θ ≈ −175 K [26], reflects the large magnetic frustration in the system [27]. The magnetic transition is accompanied by a symmetry lowering from P321 to C2 [28].…”

PPMS-based set-up for Raman and luminescence spectroscopy at high magnetic field, high pressure and low temperature

We present an experimental set-up permitting Raman and luminescence spectroscopy studies in a commercial Physical Properties Measurement System (PPMS) from Quantum Design. Using this experimental set-up, gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. The set-up is particularly suitable for the study of the spin-lattice coupling in strongly correlated oxide materials utilizing several different stimuli, e.g. magnetic and electric fields, high pressure and low temperatures. Details for the Raman extension, sample holder assembly and optical design, as well as data acquisition and measurement routine are described. Finally, we present exemplary results collected using the set-up, measured on reference materials, as well as on a correlated transition metal oxide.

“…Pyrochlores, compounds of the type A 2 B 2 O 7 (where A " Rare Earth, B " Transition Metal), are a class of frustrated magnets, in which the frustration arises from the arrangement of the magnetic ions (A and/or B ions) in the lattice [6][7][8]. Both the rare-earth atoms occupying the A sites and the transition metal elements located on the B sites form a three-dimensional network of corner-sharing tetrahedra (see Figure 1), known to display the highest degree of geometrical frustration [6].…”

Zirconate Pyrochlore Frustrated Magnets: Crystal Growth by the Floating Zone Technique

et al. 2016

This article reviews recent achievements on the crystal growth of a new series of pyrochlore oxides-lanthanide zirconates, which are frustrated magnets with exotic magnetic properties. Oxides of the type A 2 B 2 O 7 (where A " Rare Earth, B " Ti, Mo) have been successfully synthesised in single crystal form using the floating zone method. The main difficulty of employing this technique for the growth of rare earth zirconium oxides A 2 Zr 2 O 7 arises from the high melting point of these materials. This drawback has been recently overcome by the use of a high power Xenon arc lamp furnace for the growth of single crystals of Pr 2 Zr 2 O 7 . Subsequently, large, high quality single crystals of several members of the zirconate family of pyrochlore oxides A 2 Zr 2 O 7 (with A " La Ñ Gd) have been grown by the floating zone technique. In this work, the authors give an overview of the crystal growth of lanthanide zirconates. The optimum conditions used for the floating zone growth of A 2 Zr 2 O 7 crystals are reported. The characterisation of the crystal boules and their crystal quality is also presented.
