Abstract
Samples of BaFe12O19 with high multiferroid properties at room temperature (maximum polarization Pm = 48.0–9.5 μQ/cm2, residual polarization Pr = 28.0–29.5 μQ/cm2, and electric coercive field Еc = 115–120 kV/m) have been obtained for the first time using a modified ceramic technology (based on highpurity raw materials and sintering in an oxygen atmosphere with a B2O3 addition). A mechanism for the explanation of the multiferroid properties obtained has been suggested; the large practical importance of the results obtained is noted.
