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