摘要：
The compound UCo2P2 has been prepared and found to crystallize in a defective tetragonal CaBe2Ge2-type structure (space group P4/nmm). The magnetization of this ternary phosphide is linear up to 14 T at 4.2 K but its temperature dependence shows a rapid increase at 175 K and a subsequent drop at 220 K. Neutron-diffraction results at 2 K allow us to propose a model of an antiferromagnetic structure with magnetic cell (a, a, 2c) and moments on uranium sites of 1.8(1)mu(B) along the c-axis direction, while those on cobalt sites have a very small value, about 0.2(1)mu(B).
