Magnetic and resonant properties of ferrite compositions (1−x) MeFe2O4 • xP2O5 prepared by plasma spraying [Текст] / Анатолий Александрович Лепешев, Игорь Васильевич Карпов, Анатолий Васильевич Ушаков, Геннадий Ефимович Нагибин // Materials Research Express. — 2017. — Т. 4 (№ 5). — С. 056101Аннотация:
It was found that after plasma spraying and rapid quenching of ferrite compositions (1 − x)MeFe2O4 centerdot xP2O5 within the range of 0.35 < x < 0.4 for any considered compounds, transition to the x-ray-amorphous state is observed (so called concentration depended transition (CDT). This transition occurs along with modification of x-ray and Mössbauer spectra (quadrupole splitting into isomer shift) and changing their magnetic parameters: a saturation magnetization σ s, a coercive field H c and a line width of ferromagnetic resonance (FMR) ΔH. The abnormal increase of saturation magnetization σ s is revealed at T < 100 K. Particularities of changing the Curie temperature T c and a saturation magnetization σ s at different rates of quenching ferrites from the liquid state are discussed.
