Abstract Nickel zinc ferrite (NZF) and barium titanate (BT) were prepared by auto-combustion synthesis as an effective, simple and rapid method. Multiferroic composites with the general formula yNi 1− x Zn x Fe 2 O 4 −(1− y )BT ( x =0.3, 0.5, 0.7, y =0.5) were prepared by mixing NZF and BT powders in a liquid medium in the ball mill. The FEG micrographs indicated the primary particle ...
