| Abstract: | The effects of antiferromagnetic intralayer coupling and different spin values on the magnetic properties of ferromagnetic - antiferromagnetic double layers are studied using spinwave theory. In the case of antiferromag netic interlayer coupling, the temperature at which there is a crossover be tween sublattice magnetizations in each layer for different spin values is calculated, so that interesting quantum effects appear at low temperature. |

| Keywords: | spin-wave theory ferro-antiferromagnetic double layers quantum fluctuation |
