Abstract:
Magnetic properties of Zn1-xMxCr2Se4 (M=In, Ni, Al, Ga) in high magnetic field up to 14 T and at low temperatures are presented. ZnCr2Se4 belongs to the group of normal spinels with Zn2+ located at tetrahedral (A) sites and Cr3+ occupying (B) sites of the cubic close-packed array of selenium anions. Magnetic order in the compounds is connected with superexchange interactions, which are positive between the nearest neighbors and negative between the next-nearest neighbors. Substitution of one of the cations of spinel with another 3d metal causes essential changes in the cation distribution and physical properties.Keywords: antiferromagnetic materials; magnetization; magnetic moments
