Pressure effects on the Curie temperature
Tc and the spontaneous magnetization at 0K, σ
0, are reviewed systematically. The materials concerned are Ni-, Fe- and Co-based transition metal alloys and the intermetallic compounds between rare earth metals including Y, La and Th, and Fe, Co and Ni.
Experimental results of the pressure effect on
Tc,
ΔTc/
Δp, for the alloy systems are similar to the results of the compound systems, when
ΔTc/
Δp is considered to be a function of
Tc. The results of the pressure effects on both
Tc and σ
0 are analysed on the basis of the itinerant electron model. Finally the pressure effects on the magnetocrystalline anisotropy and the internal field, and some materials for which the pressure effect is to be investigated are briefly presented.
