Abstract
A domain wall model consisting of semicylindrical domains at the surface of the material in the saturated state can be used to describe irreversible flux changes in grain-oriented 50% nickel-iron (Ni-Fe) alloys, if these flux changes are produced by pulses of magnetomotive force (mmf). This model can also be used to describe certain small-signal reversible flux changes. The resulting analysis is applicable in the saturation region and in the case of small superimposed a-c signals during a large-scale flux reversal initiated by mmf drives.Keywords
