Mn-doped Ga(As,P) and (Al,Ga)As ferromagnetic semiconductors
J. Masek, J. Kudrnovsky, F. Maca +5
A remarkable progress towards functional ferromagnetic semiconductor materials for spintronics has been achieved in p-type (Ga,Mn)As. Robust hole-mediated ferromagnetism has, howev…
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…
Interlayer coupling in ferromagnetic semiconductor superlattices
T. Jungwirth, W. A. Atkinson, B. H. Lee +1
We develop a mean-field theory of carrier-induced ferromagnetism in diluted magnetic semiconductors. Our approach represents an improvement over standard RKKY model allowing spatia…
Circuit model for spin-bottleneck resistance in magnetic-tunnel-junction devices
T. Jungwirth, A. H. MacDonald
Spin-bottlenecks are created in magnetic-tunnel-junction devices by spatial inhomogeneity in the relative resistances for up and down spins. We propose a simple electrical circuit…
Plasmon Modes and Correlation Functions in Quantum Wires and Hall Bars
U. Zuelicke, A. H. MacDonald
We present microscopic derivations of the one-dimensional low-energy boson effective Hamiltonians of quantum wire and quantum Hall bar systems. The quantum Hall system is distingui…
Electron-electron interactions and two-dimensional - two-dimensional tunneling
T. Jungwirth, A. H. MacDonald
We derive and evaluate expressions for the dc tunneling conductance between interacting two-dimensional electron systems at non-zero temperature. The possibility of using the depen…
