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$_{\textrm{N}}$ = 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 $\mu_{\textrm{eff}}$ = 3.71 $\mu_{\textrm{B}}/$U and the Weiss temperatures of $\theta_{\textrm{P}}^{[100]} = -900$ K and $\theta_{\textrm{P}}^{[001]} = -500$ K for H $\parallel$ [100] and H $\parallel$ [001] respectively. The characteristic Kondo-like temperature for URhIn$_{5}$ yields T$_{\textrm{K}} =$ 125 K.
