Magnetic characteristics of nanocrystalline GaMnN films deposited by reactive sputtering
(2013-01-29)
The magnetic characteristics of Ga1-xMnxN nanocrystalline films (x = 0.08 and x = 0.18), grown by reactive sputtering onto amorphous silica substrates (a-SiO2), are shown. Further than the dominant paramagnetic-like ...
Anomalous lattice parameter of magnetic semiconductor alloys
(AMER INST PHYSICS, 2009)
The addition of transition metals to III-V semiconductors radically changes their electronic, magnetic, and structural properties. We show by ab initio calculations that in contrast to the conventional semiconductor alloys, ...

Effect of spin-polarized subbands in the inhomogeneous hole gas providing the indirect exchange in GaMnAs bilayers
(Elsevier B.V., 2004-05-01)
The magnetic order resulting from the indirect exchange in the metallic phase of a (Ga,Mn)As/GaAs double layer structure is studied via Monte Carlo simulation. The polarization of the hole gas is taken into account, ...
Spin-polarized transport in II-VI diluted magnetic semiconductors superlattices
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We studied the spin-polarized charge densities in II-VI-based diluted magnetic superlattices formed of p-doped ZnTe:Mg/ZnTe:TM/ZnTe:Mg non-magnetic/magnetic/non-magnetic layers, with TM standing for transition metal. The ...
Ultrafast spin dynamics in II-VI diluted magnetic semiconductors with spin-orbit interaction
(American Physical Society, 2015-05)
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic semiconductors in the presence of spin-orbit interaction. Our goal is to explore the interplay or competition between the exchange sd coupling ...
Study of the oxygen vacancy influence on magnetic properties of Fe- and Co-doped SnO2 diluted alloys
(SPRINGERNEW YORK, 2012)
Transition-metal (TM)-doped diluted magnetic oxides (DMOs) have attracted attention from both experimental and theoretical points of view due to their potential use in spintronics towards new nanostructured devices and new ...
Sonochemical synthesis and magnetism in co-doped ZnO nanoparticles
(2013-07-01)
The understanding and control of ferromagnetism in diluted magnetic semiconducting oxides (DMO) is a special challenge in solid-state physics and materials science due to its impact in magneto-optical devices and spintronics. ...
