- Abstract
The magnetoelectric (ME) properties of sol-gel grown BiFeCoO3 (BFCO) nanoceramics, with different sizes, were investigated at room-temperature. X-ray diffraction (XRD) measurement was performed to investigate structural properties of the samples understudy. Magnetic field-dependent dielectric permittivity has been systematically investigated in the frequency range of 20 Hz to 1 MHz. To ensure the origin of magnetodielectric response, the magnetoimpedance (MI) spectroscopy was adopted using equivalent circuit model. The a.c. conductivity was found to obey the Jonscher's universal power law. The modifications in spiral spin structure in the BFCO nanoparticles with size less than 62 nm significantly affect the ME coupling parameters.
