Abstract—
We propose microwave activation of the synthesis of yttrium ferrite doped with different cobalt concentrations. According to X-ray diffraction results, the synthesized YFeO3 and YСохFe1 –хO3 (with up to a 15% nominal doping level) are essentially free from impurity phases. The powders range in particle size from 20 to 60 nm (according to transmission electron microscopy data). Cobalt doping of YFeO3 raises the magnetic permeability of the material and broadens its hysteresis loop, which is due to an increase in spin–orbit interaction energy.
