Abstract

Hexagonal Z-type Sr₃Co₂Fe₂₄O₄₁ ferrite particles are prepared in this study by hydrothermal method. The effects of synthesis condition on the phase transformation, microstructure, and magnetic properties of the particle are investigated. SEM, FTIR spectroscopy, and vibrating sample magnetometry are used for characterization. Magnetic measurement results show that the coercive field remains lower than that of bulk specimens which is probably due to the easy reversal of magnetic moments caused by the shape of particles while the remanent specific magnetization and saturation specific magnetization are close to those of a ceramic hexaferrite.
