• The structure, magnetic properties and thermal properties of the ζ-phase and μ-phase of the Pd_3Mn_2 alloy were investigated. The ζ-phase has a b.c.t. lattice with the CsCl-type superstructure, while the μ-phase has a modified form of the ζ-phase superstructure. Both phases are antiferromagnetic, but in the μ-phase the susceptibility below the Neel point is strongly dependent on the field strength. The excess heat absorption at the Neel point is 510 cal./mol. (Pd_<15>Mn) for the μ-phase, 890 cal./mol. (Pd_<15>Mn) for the ζ-phase, and the heat of transformation from μ to ζ is 180cal./mol. (Pd_<0.6>Mn_<0.4>) These results are discussed on the basis of the two sublattice model of an antiferromagnet.
