摘要	The method of the double-time-temperature Green function is used to study theoretically the magnetic properties of layered Heisenberg ferrimagnets. The sublattice magnetization is calculated for different interlayer coupling strengths in the whole range of temperatures. According to the extent to which the interlayer coupling suppresses the two-dimensional spin fluctuations, we divide the low-temperature regime into two parts and give the asymptotic expressions for sublattice magnetization in two low-temperature regimes and in the vicinity of the Curie temperature, respectively. We also discuss the dependence of the Curie temperature on the interlayer coupling strength.
