Crystal structures and magnetic properties of Pd–Mn–Te alloys have been investigated by means of X-ray diffraction and magnetic balance, respectively. It has been found that the alloys of near-stoichiometric compositions are of Cl_b type structure and form a solid solution having lattice parameters of about 6.269∼6.274 Å at room temperature in the composition range of Pd_1.0125Mn_0.975Te_1.0125∼Pd_0.975Mn_1.05Te_0.975. The compound PdMnTe was assumed to be antiferromagnetic from the temperature dependence of magnetic susceptibility, the Néel temperature being 22°K. The paramagnetic Curie temperature and the effective Bohr magneton number per Mn atom were evaluated to be 25±3°K and 5.28, respectively.
