TL;DR: In this article, the preparation and room temperature Raman study of polycrystalline magnetoelectric BiFeO 3 (BFO) material is reported, where all the 13 Raman modes predicted by group theory ( Γ Raman,R3c =4 A 1 + 9 E ) for R3c structure of BFO are observed in the present work.

TL;DR: In this paper, the effect of varying the incident laser power up to 40 mW was studied in all forms of the samples, and it was shown that the inverse spinel structure remains robust, and no trace of laser-induced oxidation was observed.

TL;DR: In this article, superparamagnetic nickel ferrite single phase nanoparticles with the average crystallite size of ∼9nm have been synthesized at a low temperature (220°C) by the sol-gel auto-combustion method.

TL;DR: It has been proposed that very high coercivity (9.47 kOe) is the result of the magnetic anisotropy, strain, and disorder of the surface spins developed by covalently bonded oleic acid to the surface of CoFe(2)O(4) nanoparticles.

TL;DR: In this paper, a comparative analysis of local and global structures on poled and unpoled NBT specimens using electron, x-ray, and neutron diffraction in conjunction with first-principles calculation, dielectric, ferroelectric, and piezoelectric measurements is presented.
