Abstract

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 Pd-Mn-Te alloys of stoichiometric composition is a Clb type and forms a solid solution having lattice parameters of about 6.269∼6.274 Å at room temperature in the composition range of Pd1.01<SUB>25</SUB>Mn0.97<SUB>5</SUB>-Te1.01<SUB>25</SUB>∼Pd0.97<SUB>5</SUB>Mn1.05Te0.97<SUB>5</SUB> alloys. Moreover the compound PdMnTe was supposed to be antiferromagnetic from the temperature dependence of magnetic susceptibility and reciprocal magnetic susceptibility, the Néel temperature being 22°K. The paramagnetic Curie temperature and paramagnetic effective Bohr magneton number per Mn atom were evaluated to be 25°±3°K and 5.28 μB, respectively.
