Room-temperature ferromagnetism in dielectric GaN(Gd)
V. I. Litvinov, V. K. Dugaev
We present an explanation of recently observed giant magnetic moment and room-temperature ferromagnetism in the dielectric GaN doped with Gd. Our approach uses the polarization mec…
Exchange interaction of magnetic impurities in graphene
V. K. Dugaev, V. I. Litvinov, J. Barnas
The indirect exchange interaction between magnetic impurities localized in a graphene plane is considered theoretically, with the influence of intrinsic spin-orbit interaction take…
Weak antilocalization and zero-field electron spin splitting in AlGaN/AlN/GaN heterostructures with a polarization induced two-dimensional electron gas
C. Kurdak, N. Biyikli, U. Ozgur +2
Spin-orbit coupling is studied using the quantum interference corrections to conductance in AlGaN/AlN/GaN two-dimensional electron systems where the carrier density is controlled b…
Polarization-induced Rashba spin-orbit coupling in structurally symmetric III-Nitride quantum wells
V. I. Litvinov
The effective linear coupling coefficient and the total spin-splitting are calculated in Ga- and N- face InGaN quantum wells. Alloy content, geometry, and gate voltage affect an in…
A new mechanism of exchange interaction in ferromagnetic semiconductors
V. K. Dugaev, V. I. Litvinov, J. Barnas +1
We propose a new mechanism of indirect exchange interaction, which can be responsible for the ferromagnetic ordering in Mn-doped semiconductors (like GaMnAs) at low carrier concent…
Ferromagnetism in magnetically doped III-V semiconductors
V. I. Litvinov, V. K. Dugaev
The origin of ferromagnetism in semimagnetic III-V materials is discussed. The indirect exchange interaction caused by virtual electron excitations from magnetic impurity level in…
