Abstract

We report on synthesis and anisotropic physical properties of URhIn5_{5}. High quality single crystals were grown in In-flux. The compound undergoes a second order phase transition into an antiferromagnetic state at TN_{\textrm{N}} = 98 K. The transition is field independent up to 9 T. An increase of the resistivity ρ\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 χ\chi = M/H exhibits a strong anisotropy. Above T == 200 K, χ\chi(T) follows Curie-Weiss law with the effective moment of μeff\mu_{\textrm{eff}} = 3.71 μB/\mu_{\textrm{B}}/U and the Weiss temperatures of θP[100]=900\theta_{\textrm{P}}^{[100]} = -900 K and θP[001]=500\theta_{\textrm{P}}^{[001]} = -500 K for H \parallel [100] and H \parallel [001] respectively. The characteristic Kondo-like temperature for URhIn5_{5} yields TK=_{\textrm{K}} = 125 K.
