Structure and Magnetic and Electric Properties of Bismuth Niobates Doped with d Elements:IV.Magnetic Behavior of Chromium-Containing Solid Solutions with the Structure of Bismuth Niobate,Bi5Nb3O15

摘要

The magnetic susceptibility and electrophysical properties of chromium-containing Bi5Nb_(3-3x)· Cr_(3x)O_(15-delta)solid solutions with the perovskite-like structure were studied.Parameters of exchange interactions in the dimeric clusters of chromium atoms and also the distribution of chromium monomers and dimers in the solid solutions were calculated.
