摘要：

We have studied a modification of the coherent rotation mechanism in order to include the possibility of reversal by domain wall motion. By the superposition of independent contributions a vector hysteresis model is obtained, which allows for the distribution of quenched-in anisotropy. We applied the model to the description of hysteresis loops in nanocrystalline soft materials subjected to field annealing to induce macroscopic anisotropy. (C) 2000 Elsevier Science B.V.
