Origin and Control of Ferromagnetism in Dilute Magnetic Semiconductors and Oxides
TLDR
In this article, the present understanding of the hole-mediated ferromagnetism in magnetically doped semiconductors and oxides as well as the origin of high temperature ferromagnetic magnetism in materials containing no valence band holes is reviewed.Abstract:
The author reviews the present understanding of the hole-mediated ferromagnetism in magnetically doped semiconductors and oxides as well as the origin of high temperature ferromagnetism in materials containing no valence band holes. It is argued that in these systems spinodal decomposition into regions with a large and a small concentration of magnetic component takes place. This self-organized assembling of magnetic nanocrystals can be controlled by co-doping and growth conditions. Functionalities of these multicomponent systems are described together with prospects for their applications in spintronics, nanoelectronics, photonics, plasmonics, and thermoelectrics.read more

A Cu2+ ion–F Center Complex View on the Photoluminescence Quenching and Correlating Ferrimagnetism in (Cu2+/Cu12+)0.044Zn0.956O Electrospun Nanobelts
TL;DR: Electron paramagnetic resonance spectra reveal that there is strong anisotropic spin-orbit interaction between the Cu(2+) ion and F center in the (Cu2(+)/Cu1(2+))0.044Zn0.956O NBs, which enables the potential application of tuning of the optical and ferrimagnetic properties through strain and F-center engineering.

TL;DR: In this paper, a strong interaction between the Mn atoms in these nanocolums is demonstrated by x-ray absorption spectroscopy, giving rise to a ferromagnetic character as observed through magnetometry and xray magnetic circular dichroism.

The Electronic and Magnetic Effects of 3d Transition Metal Impurities in Semiconductors
TL;DR: In this article, the authors focused on soft x-ray spectroscopy of the 3D transition metals and how the impurities doped into host semiconductors in small proportions can influence the host material's electronic and magnetic properties.
