Journal ArticleDOI
The single-phase multiferroic oxides: from bulk to thin film
TL;DR: In this article, the experimental status of multiferroics has been presented for both the bulk single phase and the thin film form, and a detailed overview on multiferromagnetic thin films grown artificially (multilayers and nanocomposites) is presented.
Journal ArticleDOI
Role of oxygen vacancy and Fe–O–Fe bond angle in compositional, magnetic, and dielectric relaxation on Eu-substituted BiFeO3 nanoparticles
A. Tamilselvan,Subramanian Balakumar,Mohan Sakar,Chiranjib Nayek,Pattukkannu Murugavel,K. Saravana Kumar +5 more
TL;DR: X-ray photoelectron spectroscopy confirms the shifting of the binding energy of the Bi 4f orbital, establishing Eu substitution at the Bi site, and calculation of the area under the Fe(2+)/Fe(3+) (2p) and O (1s) XPS spectra gives approximate values of the oxygen vacancies.
Journal ArticleDOI
Magnetoelectric effects of nanoparticulate Pb(Zr0.52Ti0.48)O3–NiFe2O4 composite films
