Magnetic Interactions in Granular Paramagnetic-Ferromagnetic GaAs:Mn/MnAs Hybrids
The paramagnetic-ferromagnetic hybrid structure with a Curie temperature above room temperature formed by metallic MnAs clusters embedded in a... -
Exchange Interactions and Magnetic Percolation in Diluted Magnetic Semiconductors
We propose a theory that combines first-principles evaluations of interatomic exchange interactions with a classical Heisenberg model and Monte Carlo... -
Carrier Induced Ferromagnetism in Concentrated and Diluted Local-Moment Systems
For modeling the electronic and magnetic properties of concentrated and diluted magnetic semiconductors we use the s-f model (ferromagnetic... -
The Role of Interstitial Mn in GaAs-Based Dilute Magnetic Semiconductors
Ferromagnetic (Ga,Mn)As continues to be the subject of intense research due to the interesting physical properties and possible spin-electronics... -
An Origin of CMR: Competing Phases and Disorder-Induced Insulator-to-Metal Transition in Manganites
We theoretically explore the mechanism of the colossal magnetoresistance in manganese oxides by explicitly taking into account the phase competition... -
Domain-Wall Dynamics in Nanowiresand Nanostrips
In nanowires or nanostrips, the magnetic domain walls have structures that depend sensitively on the transverse sizes of these samples. These... -
Domain-Wall Dynamicsin Magnetic Logic Devices
Domain walls propagate very well through magnetic nanowires and have been used to demonstrate a logic scheme in which the two stable magnetization... -
Growth and Magnetotransport Properties of Thin Co2MnGe Layered Structures
Co2MnGe and other related Heusler alloys are investigated in the context of magnetotransport properties in multilayer (ML) structures. The most... -
