Pressure dependence of the magnetization of fcc Fe-Ni alloys including Invar alloy is calculated on the basis of a simple band model. This quantity is closely related to the pressure dependence of the critical composition which bounds the strong ferromagnetic state in Ni-rich region and the paramagnetic state in Fe-rich region. In the calculation, we use a step-type density of states curve and assume that there is fluctuation in the local composition characterized by a Gaussian distribution function. Calculated result is about a fifteenth in magnitude of the observed ones, but the variation with composition is exactly similar to each other.
