Abstract
It was found that after plasma spraying and rapid quenching of ferrite compositions (1 − x)
MeFe2O4 · 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 σs, a coercive field
Hc and a line width of ferromagnetic resonance (FMR) ΔH. The abnormal increase of saturation
magnetization σs is revealed at Т < 100 K. Particularities of changing the Curie temperature Tc and a
saturation magnetization σs at different rates of quenching ferrites from the liquid state are discussed.

(2017-06)Abstract—The influence of the quench rate on structuring in spinel ferrites has been studied. It has been found that, when the quench rate is increased, the equilibrium spinel structure gradually becomes disordered. At the ...
