There was investigated the change of magnetization of non-stehiometric pirrotites depending on the concentration of vacancies in their structure. For the first time in the frame of the model of the four-sub-grate ferri-magnetic it is given a theoretical description of magnetic transformations in non-stechiometric ferri-magnetics. For explaining the effect of the ordering of vacancies it is used the method of the secondary quantization. It should be noted that the operators correspond to the quantum statistics of Pauli. The calculations are made considering the interactions between the cat ion vacancies. It is noted that the appearance of the vacancy interaction is explained by breaking the connections of d-electronic tracks and forming of non-compensated electrical charge on the vacant unit consequently.
