“…Uranium intermetallics in particular span the spectrum of materials properties from magnetism to superconductivity and hidden order to heavy fermions with strongly correlated 5f-electrons [3][4][5][6]. Since these materials are driven by such interactions they are particularly amenable to tuning via the application of pressure, doping, and magnetic fields [7][8][9][10][11]. Within uranium intermetallics, the uranium monopnictides and chalcogenides have garnered a great deal of attention because of their varied magnetic states supported by a simple crystal structure.…”

In pulsed magnetic fields up to 65T and at temperatures below the Néel transition, our magnetization and magnetostriction measurements reveal a field-induced metamagnetic-like transition that is suggestive of an antiferromagnetic to ferrimagnetic ordering. Our data also suggests a change in the nature of this metamagnetic-like transition from second-to first-orderlike near a tricritical point at T tc ~145K and H c~5 2T. At high fields for H>H c we found a decreased magnetic moment roughly half of the moment determined by neutron powder diffraction. We propose that the decreased moment and lack of saturation at high fields indicate the presence of a field-induced ferrimagnetic state above the tricritical point of the H-T phase diagram for USb 2 .

“…Hence O scales H~ in the model. Furthermore, it was found that (dTc/d p) (dp/dO) determined for a particular compound follows the slope of T c versus O dependence for compounds of this series [6,7]. Thus we propose the magnetic phase diagram shown in Fig.…”

Maxa Borna, 9, Poland Abstract A linear increase in the critical field Hc (> 200 kOe) with pressure p (0-0.5 GPa) was observed for the spin reorientation transition in U3As 4 by measurements of magnetisation along the (100) axis at 5 K; dHc/d p = 76 kOe/GPa. An interpretation of the results and a magnetic phase diagram for the U3X 4 pnictides are proposed.

“…These two uniaxial antiferromagnets show metal-like carrier concentrations equal to 1.2 and 0.53 e/f.u. [17], respectively. They do not show, however, the change of thermoelectric power sign below TN , which was observed for USb [8].…”

Resistivity p(T) and absolute thermoelectric power S(Τ) have been measured for USb single crystaJs characterized by dicherent residual resistivity ratios, RRR = p(300 K)/p(4.2 K). A 50 μV/K peak of S(Τ) observed at 40 K for high RRR crystal vanishes for low RRR one. The p α Τ4 dependence observed below 40 K changes to the p α Τ5/2 one. These variations are ascribed to reduction of the magnoii drag echect by an increased incoherent magnetic scattering of carriers, possibly induced by a small change of composition. Resistivity anomaly is analysed above the antiferromagnetic transition temperature TN. We have found that resistivity decreases as t In t in the range 0.02 < t < 0.35, where t = (Τ -TN)/TN. It is ascribed to a semimetallic character of this compound.
