摘要：
The magnetic properties of ferromagnetic superlattices with antiferromagnetic interlayer coupling are studied by the use of a Green's function method which considers the quantum nature of Heisenberg spins. The sublattice magnetizations and the total magnetizations are calculated for different sets of interaction parameters over the whole range of temperatures. We have obtained some interesting results: (i) At low temperatures, there is a crossover of the two magnetizations in each sublattice corresponding to two different interlayer interactions. (ii) The compensation temperature is found within a certain range of parameters.
