Abstract

The composites of Fe1.2Ga0.8O3 (metal doped hematite) and Co1.25Fe1.75O4 (spinel ferrite) have been prepared by weight mixing method. X-ray diffraction pattern and Raman spectroscopy have been used to confirm the coexistence of rhombohedral structure of Fe1.2Ga0.8O3and spinel structure of Co1.25Fe1.75O4. The Energy dispersive analysis of X-ray spectrum has been used to determine elemental composition of the composite samples. The ferromagnetic and dielectric properties of the material have been studied at room temperature by adjusting weight ratio of Fe1.2Ga0.8O3 and Co1.25Fe1.75O4components. The samples have shown properties of ferromagnetic-dielectric material with electrical conductivity 10-8–10-11 S/cm, dielectric constant in the range 0.002-20 and extremely low dielectric loss (<1) above 1 kHz. The composite samples showed good signature of ferroelectric properties, although polarization leakage has increased in the composite samples with the increase of Fe1.2Ga0.8O3 content. The results could be interesting for designing suitable ferromagnetic and ferroelectric composite materials for possible applications in spintronics devices, whose operation can be controlled by simultaneous applications of electric field and magnetic field
