Mössbauer study of copper ferrite diluted by Ga3+ and Al3+ ions

Mössbauer spectra of the CuGa x Al 2 x Fe 2 − 3 x O 4 system ( x = 0.1, 0.2, 0.3, 0.4, 0.5) have been studied at a temperature of 295 K. The results obtained are compared with Mössbauer data for the CuGa x Al x Fe 2−2 x O 4 system. It is established that the hyperfine magnetic fields H B (for octahe...

Zusammenfassung:Mössbauer spectra of the CuGa x Al 2 x Fe 2 − 3 x O 4 system ( x = 0.1, 0.2, 0.3, 0.4, 0.5) have been studied at a temperature of 295 K. The results obtained are compared with Mössbauer data for the CuGa x Al x Fe 2−2 x O 4 system. It is established that the hyperfine magnetic fields H B (for octahedral sites) and H A (for tetrahedral sites) for ferrites in both systems with ferrimagnetic ordering decrease linearly depending on the total number of nonmagnetic ions in octahedral and tetrahedral sites of the two systems.
