Remagnetization Experiments in Mn1+xFe2−xO4

Abstract

The remagnetization time τ has been measured as a function of external field H for a series of manganese ferrites, Mn1+xFe2−xO4. The physical properties of these compounds which enter into the domain wall model of Menyuk and Goodenough and the rotational model of Gyorgy have also been measured. It is found that α, the loss constant, is critical to the correlation of data with theory, and that neither theory can be unequivocally proved until more insight into the remagnetization process loss mechanism is acquired.
