Abstract

Mg-substituted ferrite Li_0.5Mg_xFe_1.25-(2/3)xCr_1.25O₄ (0 ≤ x ≤ 0.3) was studied using X-ray diffraction, Mössbauer spectroscopy and magnetic measurements. X-ray diffraction patterns show that all samples have cubic spinel structure. The temperature-dependent magnetic measurements revealed that the compensation point T_K of Li_0.5Cr_1.25O₄ starts to approach the Neel temperature T_N as Mg²⁺ substitution of Fe³⁺ increases, until the compensation disappears at x = 0.3. This effect is investigated in relation to the cation distribution established using the Mössbauer study of this system.
