| Abstract: | 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. |
