d0 Perovskite-Semiconductor Electronic Structure
R. Bistritzer, G. Khalsa, A. H. MacDonald
We address the low-energy effective Hamiltonian of electron doped d0 perovskite semiconductors in cubic and tetragonal phases using the k*p method. The Hamiltonian depends on the s…
Theory of I-V Characteristics of Magnetic Josephson Junctions

We analyze the electrical characteristics of a circuit consisting of a free thin-film magnetic layer and source and drain electrodes that have opposite magnetization orientations a…
Magnetic interactions of substitutional Mn pairs in GaAs
T. O. Strandberg, C. M. Canali, A. H. MacDonald
We employ a kinetic-exchange tight-binding model to calculate the magnetic interaction and anisotropy energies of a pair of substitutional Mn atoms in GaAs as a function of their s…
Magnetic properties of substitutional Mn in (110) GaAs surface and subsurface layers
