Magnetic and Dielectric Properties of Barium Magnesium Hexaferrite Epoxy Resin Composite Film

Article Preview

Abstract:

The W type barium magnesium hexaferrite powder with chemical composition BaMg2Fe16O27with CTAB surfactant was synthesized using solvent free synthesis method. The precursor was calcinated at 950 °C for 6 h in a muffle furnace and then slowly cooled to room temperature in order to obtain barium magnesium hexaferrite powder. The flexible epoxy thick film of Ba-Mg hexaferrite/epoxy composite was fabricated using suitable amount of hardener and curing agent. The field-dependent magnetic properties of the hexaferrite sample were investigated at room temperature using a vibrating sample magnetometer (VSM) with a maximum applied field of 15 kOe. The dielectric measurements were taken at room temperature within the frequency range to 100 Hz to 2 MHz.
