Abstract
ABSTRACT
Recently, multiferroic materials such as BiFeO3 have fascinated researchers for their potential application in memory storage devices. However, high leakage, weak magnetism and magnetoelectric coupling in this system restrict its practical applications. To solve this, the octahedra tilt influencing electrical, magnetic and thermal properties of polycrystalline Bi0.9Co0.1FeO3 ceramics via solid state route is studied here. Cobalt doped BiFeO3 affect the structural arrangement and tunes the crystal engineering of BiFeO3. In particular, the temperature-dependent dielectric behaviour of Bi0.9Co0.1FeO3 shows a significant dielectric anomaly corresponding to the magnetoelectric coupling in this sample. Further, the maximum magnetization of Bi0.9Co0.1FeO3 is 8.70 emu/ g which is two orders higher in magnitude compared to pristine BiFeO3.
期刊介绍：
Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include:
-structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.)
-geophysical phase transitions
-metal-insulator phase transitions
-superconducting and superfluid transitions
-magnetic phase transitions
-critical phenomena and physical properties at phase transitions
-liquid crystals
-technological applications of phase transitions
-quantum phase transitions
Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
