Abstract

Multiferroic particulate composites $(1 - x)$ Ba $_{0.95}$ Ca $_{0.05}$ Ti $_{0.89}$ Sn $_{0.11}$ O $_{3}$ - $(x)$ CoFe $_{2}$ O $_{4}$ with ( $x$ = 0.1, 0.2, 0.3, 0.4 and 0.5) have been prepared by mechanical mixing of the calcined and milled individual ferroic phases. X-ray diffraction and Raman spectroscopy analysis confirmed the formation of both perovskite Ba $_{0.95}$ Ca $_{0.05}$ Ti $_{0.89}$ Sn $_{0.11}$ O $_{3}$ (BCTSn) and spinel CoFe $_{2}$ O $_{4}$ (CFO) phases without the presence of additional phases. The morphological properties of the composites were provided by using Field Emission Scanning Electron Microscopy. The BCTSn-CFO composites exhibit multiferroic behavior at room temperature, as evidenced by ferroelectric and ferromagnetic hysteresis loops. The magnetoelectric (ME) coupling was measured under a magnetic field up to 10 kOe and the maximum ME response found to be 0.1 mV /cm/ Oe for the composition 0.7 BCTSn-0.3 CFO exhibiting a high degree of pseudo-cubicity and large density.
