层状反铁磁体低温性质的理论计算

Theoretical Calculation of Low-Temperature Properties of Layered Anti-Ferromagnets

用自旋波理论研究了层内是反铁磁性耦合的反铁磁体的低温性质，找到了零温及有限温区的子晶磁化强度和内能与层间耦合间的变化关系，并给出有了有限温区内磁比热和平行磁化率与层间耦合之间的变化关系．

This article studies the low?temperature properties of anti?ferromagnet with ferromagetic coupling within layer using the spinwave throry.It summarizes the relationship between sub?lattice magnetization and internal energy at zero temperature and within limited region of temperature.It also gives the variation relations between specific heat and parallel susceptibilities and interlayer coupling within limited region of temperature.
