Anisotropic magnetic properties of URhIn${}_5$ compound

Abstract

We report on synthesis and anisotropic physical properties of URhIn${}_5$. High quality single crystals were grown in In-flux. The compound undergoes a second order phase transition into an antiferromagnetic state at T${}_{\text{N}}$ = 98 K. The transition is field independent up to 9 T. An increase of the resistivity $\rho$ with j along the [100], [110] and [001] tetragonal axis indicates a spin-density-wave induced order with the gap opening first along the [001] direction. The magnetic susceptibility $\chi$ = M/H exhibits a strong anisotropy. Above T $=$ 200 K, $\chi$(T) follows Curie-Weiss law with the effective moment of ${\mu }_{\text{eff}}$ = 3.71 ${\mu }_{\text{B}}/$U and the Weiss temperatures of ${\theta }_{\text{P}}^{[100]}=-900$ K and ${\theta }_{\text{P}}^{[001]}=-500$ K for H $\parallel$ [100] and H $\parallel$ [001] respectively. The characteristic Kondo-like temperature for URhIn${}_5$ yields T${}_{\text{K}}=$ 125 K.
