摘　　要：用Ｆｅｒｒａｒｉ法解出能量方程，并藉助于外场的ｈ－α平面，研究了Ｓｔｏｎｅｒ－Ｗｏｈｌｆａｒｔｈ单畴微粒问题，揭示了磁化矢量Ｍ的运动的两种模式，导得了转动磁滞损耗Ｗｒ的３个表式．The historical Stoner-Wohlfarth's problem is studied by solving the energy equation with Ferrari method and using h-α plane. The authors find that there are two modes for the movement of the magnetized vector M and derive the expressions on hysteresis loss of rotation magnnetization under applied rotating field and ac field rigorously.

关 键 词：磁畴 磁化强度 磁各向异性 磁滞损失 S-W问题
