Interrelation of magnetic properties with the crystal structures of $MeFe_2Se_4$ (Me= Ti; V; Cr; Fe; Co; Ni) compounds

Özet

Magnetization of MeFe2Se4 (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.
