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 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 article, thin films of Cu 2 O and CuO are deposited by RF reactive sputtering at different substrate temperatures, and they are identified by grazing angle X-ray diffraction (GAXRD).

TL;DR: In this article, a Mn doped magnetoelectric BiFeO3 system is studied using X-ray diffraction, scanning electron microscopy, energy dispersive x-ray analysis (EDX), Mossbauer spectroscopy at room and high temperatures, differential scanning calorimetry (DSC), high temperature magnetization, dielectric constant measurements and XPS are used to characterize the samples.
