Popis:	A generalized form of mean field theory and procedures for applying it to analyze experimental data on the temperature dependence of the saturation magnetization or the effective gyromagnetic factor of n‐component amorphous transition‐metal–rare‐earth alloys are outlined. This analysis yields the spin values of each component and the effective exchange interaction energies between them, from which other magnetic properties such as the subnetwork magnetizations and the macroscopic exchange stiffness can be calculated. Examples of application of this mean field procedure are given.
