Influence of annealing on the chemical composition of nanocomposites with the ferromagnetic grains in the CaF2 dielectric matrix

Thermochimica Acta. 2019. Vol. 676. P. 224-233.

In the paper the content of individual elements (Fe, Co, Zr, Ca and F) contained in nanocomposites FeCoZr ferromagnetic alloy in the CaF2 transparent ceramics dielectric matrix, depending on the content of the metal
phase x was determined by the X-ray diffusion microanalysis (EDX) method. The nanocomposites were made by
sputtering by argon ions. Investigations of changes in the chemical composition of nanocomposites under the
influence of high-temperature treatments were carried out using the thermogravimetry method in the temperature
range from 25 °C to 1000 °C with a temperature increase rate of 10 °C/min. On the basis of the research,
a model of changes of the structural-phase state of nanogranular layers of ferromagnetic alloy Fe45Co45Zr10 in
the transparent ceramics CaF2 matrix occurring under the influence of high-temperature treatments was proposed.
