摘要：

In this paper we report the observed magnetic interactions in barium hexaferrite tapes as a function of dispersion milling time and orientation. Measurement of the interaction state is obtained by comparing the magnetizing and demagnetizing remanence curves. Variation in the interactions as a function of dispersion milling time in longitudinally and non-oriented tapes indicates substantial changes in the interaction state of the constituent magnetic particles. In particular the oriented tape samples exhibit an increasing net magnetizing interaction effect, whereas the non-oriented samples show a decreasing net magnetizing effect. © 1990 IEEE
