ON THE IRREVERSIBLE SUSCEPTIBILITY OF A TEXTURED STONER-WOHLFARTH ENSEMBLE

For models containing both reversible and irreversible magnetization p rocesses the time-dependent irreversible susceptibility and the differ entiated remanence curve differ from each other. To demonstrate this, both quantities were calculated for a non-interacting Stoner-Wohlfarth ensemble in dependence on the degree of alignment, the magnitude and the application time of an opposite field. For the differentiated rema nence curve at t = 0 s an analytical expression was derived. For gener al times the calculation was carried out numerically.
