摘要：
An analysis of the magnetoelastic coupling and the magnetocrystalline anisotropy in rare earth intermetallic compounds has been undertaken on the basis of a microscopic description. Crystal electric field and exchange interaction have been considered as the main contribution to the free energy in order to explain the behaviour. Magnetostriction measurements on cubic (RAl2, RNi2) and uniaxial (RCo5 and R2Fe14B) compounds are reported. A single ion origin for the magnetocristalline anisotropy of the R3+ ion has been tested, which has allowed a complete and reliable description of the spin reorientation processes because of the interplay of competing anisotropies. © 1990.
