Abstract

Pressure effects on magnetic properties of Cu₃Au-type ordered alloys MPt₃ (M = V, Cr, Mn, Fe, Co) are studied based on their electronic band structures calculated by using a linearized augmented-plane-wave (LAPW) method. It is found that the magnetization in the ferromagnetic state of CoPt₃ decreases more rapidly with increasing pressure than in the magnetically ordered states of the other alloys. It is expected that the magnetic moment of Pt atoms in CrPt₃ (or VPt₃) becomes parallel to that of Cr (or V) atoms under high pressure.
