  The kondo lattice compound UAu0.66Sb2 belongs to a family of numerous ternary compounds crystallizing in a tetragonal structure of the HfCuSi2-type(space group P4/nmm).The magnetic susceptibility and electrical resistivity of it have been investigated.The antiferromagnetic transition at TN=71K and metamagnetic transitions are found in this single crystal.The staircase-like hysteresis have been observed both in magnetoresistance and magnetic susceptibility.We present the field-temperature phase diagram of UAu0.66Sb2.
