Structural, Magnetic, and Dielectric Properties of SrFe12O19-Ba0.85Ca0.15Ti0.9Zr0.1O3 Composites
Structural, magnetic, and dielectric properties of \(x\)SrFe12O19-(1-\(x\))Ba0.85Ca0.15Ti0.9Zr0.1O3 multiferroic composite prepared by sintering the composite mixture of sol-gel synthesized SrFe12O19 (SrF) and Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCTZ) are reported. Structural parameters (lattice parameter, bond length, and lattice strain) of parent phases in their pure and composite forms are correlated to indicate the lattice interaction between the two phases. The magnetic moment per gram of SrF (\({M}_{SrF}\)) in the composite is higher than that in the SrF, related to the changes in the Fe-O-Fe bond angles. The room temperature dielectric response of the composites in the 100 Hz–10 MHz frequency range is modeled by the Cole–Cole relaxation and Jonscher power law equations to mark the different contributions (ferroelectric dipoles, charge carriers).
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
