چکیده انگلیسی
Detailed structural analysis of the X-Ray diffraction pattern of La0.9Gd0.1FeO3 (LGFO) synthesized via the solid state reaction reveals distorted perovskite structure. Magnetization studies show a characteristic of weak ferromagnetism which is believed to be induced by canted anti-ferromagnetically coupled spins. When explored in a wide temperature and frequency range, AC electrical properties reveal interesting relaxation mechanisms. LGFO exhibits relatively high dielectric permittivity (εâ²~4Ã103) close to room temperature. Temperature dependent magneto-dielectric response appears (magnetodielectric ~â5.5%) even at low magnetic field ~5 kOe. Attractive electrical, magnetic and magnetoelectric properties of the present LGFO at relatively higher temperature makes it a very promising material for application in devices.
