Abstract
Considerable increases in the initial permeability as well as the maximum permeability are known to be observed by giving magnetic annealing in 50-50 Ni-Fe alloys. In order to investigate the increases in the initial permeability, variation in Ni composition and the cooling rate from high temperature annealing are given to obtain the variable magnetocrystalline anistropy, and the relationship between these and the induced uniaxial anisotropy were investigated. From these results it is concluded that the high initial permeability was obtained when two anisotropy values are similar. Hypothesis to explain the mechanism are offered.
