The M3Fe4V6O24 (M = Cu, Zn, Mg, and Mn) Studied at High Temperatures using EPR2

Abstract

In the high temperature range (293 K to 493 K), electron paramagnetic resonance (EPR) spectra of M₃Fe₄V₆O₂₄ (M = Cu, Zn, Mg, and Mn) compounds were examined. The role of magnetic (Cu, Mn) and non-magnetic (Zn, Mg) ions in the production of magnetic resonance spectra in the M₃Fe₄V₆O₂₄ structure was investigated. The effect of temperature on EPR parameters such as resonance field, line width, and integrated intensity was investigated. In terms of distinct relaxation mechanisms and magnetic interactions in spin systems, similarities and variations in the temperature behaviour of these parameters have been studied. Additional magnetic ions (M = Mn or Cu) play a key role in the M₃Fe₄V₆O₂₄ structure, and the consequences have been studied.
