Magnetic properties of hard (CoFe2O4)–soft (Fe3O4) composite ceramics
Source abstract
Abstract
Abstract Composite ceramics of CoFe 2 O 4 /Fe 3 O 4 with different weight ratios were synthesized by Spark Plasma Sintering (SPS) at a sintering temperature of 500 °C. The X-ray diffraction patterns demonstrate that all samples are composed of CoFe 2 O 4 and Fe 3 O 4 phases. The magnetization curves for all the composite ceramic are single-step loops indicating the existence of exchange spring effect. Due to the competition between the exchange interaction and the dipolar interaction, magnetic properties like coercivity ( H c ) and remanence ( M r ) are sensitive to the weight ratio of the soft phase.
