Title: Aliovalent-ion and magnetic field induced phase transition in multiferroic BiFe 1-xTi xO 3 system
Authors: Yadav, Kamlesh Kumar
Published in: Journal of Nanoscience and Nanotechnology
Abstract: Multiferroic compounds with general formula BiFe 1-xTi xO 3 (x = 0.1, 0.2, 0.3 and 0.35) have been synthesized by conventional solid state reaction method. The effect of Ti substitution on ferroelectric and magnetic properties is studied. From X-ray diffraction (XRD) analysis, a rhombohedral to orthorhombic phase transition for x > 0.3 was observed. From SQUID measurements, a magnetic field induced phase transition has been observed in the BiFe 1-xTi xO 3 system for x = 0.3. An anomaly in dielectric constant and dielectric loss in the vicinity of antiferromagnetic Néel temperature (T N) and a small enhancement in magnetization have been observed. Magnetization measurements above room temperature showed no systematic variation in antiferromagnetic Néel temperatures on Ti substitution. Further it is seen that this system shows the coupling between electric and magnetic dipoles exhibiting magnetoelectric (ME) effect at room temperature and possess high dielectric constant. © 2011 American Scientific Publishers.
