Abstract
We show that the subnetwork exchange coupling constant λ of ferrimagnetic films is equal to the slope of the plot of the magnetic field H applied in the film plane versus the in-plane magnetization M at compensation temperature T comp i.e. H=λM at T comp. This finding enables the direct measurement of λ for ferrimagnetic magneto-optical recording thin films regardless of the complexity of the two-subnetwork problem. The experimental results are within the range predicted by the mean-field theory.
