TLDR
The presence of pure phases of both BiFeO3 (BFO) and SrFe12O19 (SRF) in Nanocomposites for x = 0.3 and 0.4 has been confirmed by Rietveld analysis of XRD data as mentioned in this paper.Abstract:
Nanocomposites (NCs) comprising (1−x) BiFeO3 (BFO) and x SrFe12O19 (SRF) (x = 0.1, 0.2, 0.3, and 0.4) have been prepared by a sol-gel route. Presence of pure phases of both BiFeO3 (BFO) and SrFe12O19 (SRF) in the NCs for x = 0.3 and 0.4 has been confirmed by Rietveld analysis of XRD data though a minor impurity phase is observed in the case of x = 0.1 and 0.2 NCs. Transmission electron micrographs of the NCs show that particles are mostly spherical with average size of 30 nm. M-H measurements at 300 and 10 K indicate predominantly ferrimagnetic behavior of all the NCs with an increasing trend of saturation magnetization values with increasing content of SRF. Dielectric constant (er) of the NCs at room temperature shows a dispersive behavior with frequency and attains a constant value at higher frequency. er − T measurements reveal an increasing trend of dielectric constant of the NCs with increasing temperature and show an anomaly around the antiferromagnetic transition temperature of BFO, which indicates...read more

The Renaissance of Magnetoelectric Multiferroics
Nicola A. Spaldin,Manfred Fiebig +1 more
TL;DR: Magnetoelectric multiferroics combine ferromagnetic magnetization and ferroelectricity in the same phase and have tremendous potential for applications, not only because they possess the properties of both parent phenomena, but also because coupling between ferromagnetism and electric polarization can lead to additional novel effects as discussed by the authors.
