Volume : II, Issue : XII, January - 2013 STUDIES ON STRUCTURAL MAGNETIC AND MAGNETOELECTRIC PROPERTIES OF THE COFE O –BA SR TIO COMPOSITES S. S. SAWANTA , P. K. GAIKWADA , M. L. DHUMALB AND A. B. PISALC Published By : Laxmi Book Publication Abstract : The magnetoelectric composites containing cobalt ferrite (CoFe O ) and 2 4
barium strontium titanate (Ba Sr -TiO ) phases were investigated. The composites 0.7 0.3 3
were prepared by standard double sintering ceramic method. The X-ray diffraction
analysis was carried out to con?rm the phases formed during sintering and also to
calculate the lattice parameters. The hysteresis measurements were done to determine
saturation magnetization (Ms), remenance magnetization (Mr) and coercivity (Hc) of
the samples. The magnetoelectric voltage coef?cient (dE/dH)H was studied as a function
of intensity of the magnetic ?eld. A large ME voltage coef?cient of about 569 ìVcm-1Oe-
1 was observed for 20% CoFe O + 80% Ba Sr TiO composite. Keywords : Article : Cite This Article : S. S. SAWANTA , P. K. GAIKWADA , M. L. DHUMALB AND A. B. PISALC, (2013).
