“…Particularly, those compounds with T = Pd and X= Sn [7] or In [8] are of interest concerning the ShSu phase formation because of the triangular coordination of the 'R' magnetic atoms. This quasi 2D structure can be described as successive 'T+X' (at z = 0) and 'R' (at z = 1/2) layers [9], with the 'R' nn and nnn disposed with the same symmetry like in SrCu 2 (BO 3 ) 2 , albeit at different relative distances.…”

Electron concentration effects on the Shastry-Sutherland phase stability in Ce2−xPd2+yIn<

The stability of a Shastry-Sutherland ShSu phase as a function of electron concentration is investigated through the field dependence of thermal and magnetic properties of the solid solution Ce2−xPd2+yIn1−z in the antiferromagnetic branch. In these alloys the electronic (holes) variation is realized by increasing P d concentration. The AF transition TM decreases from 3.5 K to 2.8 K as P d concentration increases from y = 0.2 to y = 0.4. By applying magnetic field, the ShSu phase is suppressed once the field induced ferromagnetic polarization takes over at a critical field Bcr which increases with P d content. A detailed analysis around the critical point reveals a structure in the maximum of the ∂M/∂B derivative, which is related with incipient steps in the magnetization M (B) as predicted by the theory for the ShSu lattice. The crossing of M (B) isotherms, observed in ShSu prototype compounds, is also analyzed. The effect of In substitution by P d is interpreted as an increase of the number of 'holes' in the conduction band and results in a unique parameter able to describe the variation of the magnetic properties along the studied range of concentration.

“…We have studied systematically the magnetic and other electronic properties of U2T2X compounds (T = transition metal, X = Sn or In), which crystallize in the tetragonal U3Si 2 structure [1,2]. Similar to other actinide compounds with transition metals, the character of the 5f electron states is strongly dependent on the strength of the 5-d hybridization.…”

Download date: 10 May 2018Journal of Magnetism and Magnetic Materials 140-144 (1995) AbstractMagnetic and other electronic properties are presented for the U2T2X compounds (T = late transition metal, X = Sn or In), that crystallize in the tetragonal U3Si2-type structure. They show the formation of 5f magnetic moments and antiferromagnetic ordering in compounds where weak 5f-d hybridization is expected. Near the onset of magnetic ordering strongly enhanced y-values are found. Neutron-diffraction experiments on U2Pd2Sn and U2Pd2In point to a connection between the mutual coordination of U atoms and the type of magnetic anisotropy.

High-field magnetization studies of some U2T2X compounds Fukushima, T.; Matsuyama, S.; Kumada, T.; Kindo, K.; Prokes, K.; Nakotte, H.; de Boer, F.R.; Havela, L.; Sechovsky, V.; Winand, J.M.; Rebizant, J.; Spirlet, J.C.

In case of a legitimate complaint, the Library will make the material inaccessible and/or remove it from the website. AbstractHigh-field magnetization measurements at 4.2 K on several U2T2 x (T = Ni, Rh, Pd, Pt; X = In, Sn) compounds have been performed on free and fixed powders up to 57 T. An antiferromagnetic ground state of U2Ni2Sn is corroborated by metamagnetic transitions at 30, 39 and 51 T. U2RhzSn shows one metamagnetic transition at 21 T and U2Pd2Sn two metamagnetic transitions at 39 and 45 T. U2Pt2In shows no metamagnetism up to 57 T which is in agreement with the non-magnetic ground state of this compound. The short-pulsed measurements up to 57 T are compared with previous results obtained in quasi-static fields up to 35 T.
