摘要	The method of spin-wave theory is used to study the magnetic properties of layered Heisenberg ferrimagnets. The internal energy and specific heat per site are calculated for different interlayer coupling strengths and temperatures. In the low temperature region theta(=KBT/6J) much less than theta(1)(= (2 + delta)/3), a characteristic temperature theta(0) = delta is given (delta is the ratio of ferrimagnetic interplanar coupling to planar coupling), the asymptotic expressions of internal energy and specific heat are obtained for theta much greater than theta(0) and theta much less than theta(0), respectively. It is shown that the interlayer coupling has an important effect on the magnetic properties of ferrimagnets.; The method of spin-wave theory is used to study the magnetic properties of layered Heisenberg ferrimagnets.
