摘要: The pressure dependence of the Curie temperature dTC/dP in dilute transition metal alloys and rare earth Co2 compounds is calculated combined model localised spins itinerant d electrons. It found that varies as -TC at low TC this result agrees qualitatively with many experimental results alloys. values ln TC/d V for Pd-Fe, Pd-Co, Pd-Ni, Pt-Fe Pt-Co GdCo2 compound are compared results. Pd-Fe agree well values, which show a maximum about 60K. predict there also exists (Gd-Y)Co2 Pd-Co
