Jian Wang,Jeffrey B. Neaton,Haimei Zheng,Valanoor Nagarajan,Satishchandra Ogale,B. T. Liu,Dwight Viehland,V. Vaithyanathan,Darrell G. Schlom,Umesh V. Waghmare,Nicola A. Spaldin,Karin M. Rabe,Manfred Wuttig,Ramamoorthy Ramesh +13 more
TL;DR: Enhanced polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, and combined functional responses in thin film form present an opportunity to create and implement thin film devices that actively couple the magnetic and ferroelectric order parameters.
Journal ArticleDOI
Multiferroic magnetoelectric composites: Historical perspective, status, and future directions
TL;DR: In this article, a review of mostly recent activities can be found, with a brief summary of the historical perspective of the multiferroic magnetoelectric composites since its appearance in 1972.
Journal ArticleDOI
Multiferroic BaTiO3-CoFe2O4 Nanostructures.
Haimei Zheng,Jian Wang,Samuel E. Lofland,Z. Ma,L. Mohaddes-Ardabili,T. Zhao,Lourdes Salamanca-Riba,S. R. Shinde,Satishchandra Ogale,Feiming Bai,Dwight Viehland,Y. Jia,Darrell G. Schlom,Manfred Wuttig,Alexander L. Roytburd,Ramamoorthy Ramesh +15 more
TL;DR: Thermodynamic analyses show that the magnetoelectric coupling in a nanostructured BaTiO3-CoFe2O4 ferroelectromagnet can be understood on the basis of the strong elastic interactions between the two phases.
Journal ArticleDOI
Freezing of the polarization fluctuations in lead magnesium niobate relaxors
TL;DR: In this article, the dielectric relaxation of a solid solution of lead titanate in lead magnesium niobate is found to be similar to the magnetic relaxation in spin-glass systems.
Journal ArticleDOI
Deviation from Curie-Weiss behavior in relaxor ferroelectrics.
TL;DR: It is proposed that this deviation arises due to short-range correlations between polar regions, and that these correlations at high temperatures are the precursor to a freezing of the polarization fluctuations into a glassy state.
