Conventional magnetic order in a material requires the partially filled d or f bands. The
exchange interactions between the electrons in these partially filled bands give rise to a …

In the past several decades, dilute magnetic semiconductors, particularly the dilute magnetic
oxides have evolved into an important branch of materials science due to their potential …

Amorphous and crystalline Al2O3 nanoparticles were synthesized by a sol–gel method with
postannealing at different temperatures. Magnetism measurements have indicated that all …

The increasing interest in spin-based electronics has led to a vigorous search for new
materials that can provide a high degree of spin polarization in electron transport. An ideal …

We report on the formation and transport properties of ZnO thin films which are grown by
pulsed-electron beam deposition under a low residual oxygen pressure (10− 5 mbar)⁠. ZnO …

Structural, optical and room temperature magnetic properties of Mn-doped MgO
nanoparticles with Mn fractions (5–50 at.%), were investigated. The as-prepared pure MgO …

We have measured the room temperature magnetization in Al-substituted magnesium oxide,
Mg (Al) O nanoparticles with Al fractions of up to 5 at.%. All samples, including undoped …

In present work, we have reported the room temperature ferromagnetism in lanthanum (La)-
doped magnesium oxide (MgO) nanoparticles. It has been found that the magnetic character …

We give a brief introduction to the oxide (ZnO, TiO 2, In 2 O 3, SnO 2, etc.)-based magnetic
semiconductors from fundamental material aspects through fascinating magnetic, transport …

Structural, electronic, and magnetic properties of a Heusler-type CoFeCrAl alloy have been
investigated experimentally and by model calculations, with a focus on the alloy's spin …
