NUCLEATION FIELDS AND HYSTERESIS LOOPS OF UNIAXIAL RARE EARTH-TRANSITION METAL INTERMETALLICS IN THE 2-SUBLATTICE MODEL

Nucleation fields and hysteresis loops of rare earth-transition metal intermetallics are calculated taking into account different magnetocry stalline anisotropy constants of the rare earth and the transition met al sublattices and considering the exchange coupling between the two s ublattices. Nucleation fields and hysteresis loops are determined for arbitrary angles between the applied field and the c-axis and for vari ous material parameters. The case of Fe14Nd2B is discussed in some det ail.
