Defect assisted improved room temperature ferromagnetism in Ce doped SnO2 nanoparticles
TL;DR: In this paper, the effect of Ce doping on the structural, optical and magnetic properties of SnO2 NPs has been studied systematically by using X-ray diffraction, field emission scanning microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, Raman scattering, X-Ray photoelectron spectroglobalization (XPS) and XPS, which revealed that pure and Ce doped NPs have a polycrystalline single phase tetragonal rutile structure without any detectable impurity phases.

Zener Model Description of Ferromagnetism in Zinc-Blende Magnetic Semiconductors
TL;DR: Zener's model of ferromagnetism, originally proposed for transition metals in 1950, can explain T(C) of Ga(1-)(x)Mn(x)As and that of its II-VI counterpart Zn(1)-Mn (x)Te and is used to predict materials with T (C) exceeding room temperature, an important step toward semiconductor electronics that use both charge and spin.
