Abstract :Magnetization of MeFe2Se4 insert ignore into journalissuearticles values(Me = Ti; V; Cr; Fe; Co; Ni); compounds at low temperatures has been investigated. It is shown that these compounds are ferrimagnetics with low values of specific magnetization. It is established that along the crystal axis c of a given compound, there have been carried out two types of exchange interactions; cation-cation and cation-anion-cation with different dependence of their quantity on interatomic distance.It is known that in ferri- and antiferromagnetic compounds on the basis of 3dtransition metals cation-cation as well as cation-anion-cation interactions are possible. In both cases the determinant parameter is the distance between magnetic ions. Immediate cation-cation interactions exhibit high sensitivity to change of distance between cations from the fact that interaction is proportional to the square of orbital overlap whereas interactions with the participation of intermediate anion are level considerably less dependent on distance.
