Anisotropic Magnetic Properties of URhIn₅ Compound

We report on synthesis and anisotropic physical properties of URhIn₅. High quality single crystals were grown from In self-flux. The compound undergoes a second-order phase transition into an antiferromagnetic state at $T_{N}$ = 98 K. The transition is magnetic field independent up to 9 T. An increase of the resistivity ρ 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 = M/H exhibits a strong anisotropy. Above T= 200 K, χ(T) follows the Curie-Weiss law with the effective moment of $μ_{eff}$ = 3.71 $μ_{B}$/U and the Weiss temperatures of $θ_{P}^{[100]}$ = -900 K and $θ_{P}^{[001]}$ = -500 K for H ∥ [100] and H ∥ [001], respectively. The characteristic Kondo-like temperature for URhIn₅ yields $T_{K}$= 125 K.
