Аннотация: In a real ferromagnet there are a large number of domains differing greatly in energy, so that a domain energy distribution can be introduced. The nonvanishing initial permeability and saturation on the magnetization curve allow an analytic expression to be found for this function and thus for the magnetization curve. Taking the domain interaction into account by introducing a starting field allows the B(H) dependence found to be generalized to weak fields. Analysis of ideal magnetization curves shows that the superposition on a constant field of varying fields having nonvanishing amplitudes reduces the starting field to zero, i.e., removes the magnetic interaction. The B, H plane can be thought of as a complex plane, each point of which is associated with some state of the ferromagnet. A transformation is made from the magnetization curve to the remagnetization curve by a linear transformation of this complex point. In this manner, a transformation can be made from the B(H) dependence found for weak fields to an analytic expression for the hysteresis loop in the same field range. © 1973 Consultants Bureau.
