摘　　要：采用热力学方法讨论了顺磁介质系统的力、热、磁直接效应以及它们之间的交叉效应,得到了磁化率与压缩系数、热容量与压缩系数间的关系,并讨论了力磁效应的二级近似行为.The mechanic,thermodynamic and magnetic effects and the crossing effects between them for paramagnetic materials are discussed by using the thermodynamic methods.The relations among the coefficient of compressibility,heat capacity and magnetic susceptibility are presented.The second order effects of the magnetomechanical interaction are examined.

关 键 词：顺磁介质 磁热效应 磁致伸缩 压缩系数
