Theory of t2g electron-gas Rashba interactions
Guru Khalsa, Byounghak Lee, A. H. MacDonald
The spin-degeneracy of Bloch bands in a crystal can be lifted when spin-orbit (SO) coupling is present and inversion symmetry is absent. In two-dimensional electron systems (2DES)…
Conductivity and Spin Susceptibility for the Disordered 2D Hubbard Model
Kohjiro Kobayashi, Byounghak Lee, Nandini Trivedi
The effect of disorder on a class of transition metal oxides described by a single orbital Hubbard model at half filling is investigated. The phases are characterized by the nature…
Disorder Enhanced Spin Polarization in Diluted Magnetic Semiconductors
Byounghak Lee, Xavier Cartoixa, Nandini Trivedi +1
We present a theoretical study of diluted magnetic semiconductors that includes spin-orbit coupling within a realistic host band structure and treats explicitly the effects of diso…
Spin-Orbit Effects in Diluted Magnetic Semiconductors
Byounghak Lee, Xavier Cartoixa, Nandini Trivedi +1
We present a theoretical study of diluted magnetic semiconductors that treats the local sp-d exchange interaction J between the itinerant carriers and the Mn d electrons within a r…
Field Effect Magnetization Reversal in Ferromagnetic Semiconductor Quantum Wells
Byounghak Lee, T. Jungwirth, A. H. MacDonald
We predict that a novel bias-voltage assisted magnetization reversal process will occur in Mn doped II-VI semiconductor quantum wells or heterojunctions with carrier induced ferrom…
Hole-hole correlation effects on magnetic properties of MnIIIV diluted magnetic semiconductors
T. Jungwirth, Byounghak Lee, A. H. MacDonald
The mean-field theory represents a useful starting point for studying carrier-induced ferromagnetism in MnIIIV diluted magnetic semiconductors. A detail description of…
