Chern number spins of Mn acceptor magnets in GaAs
T. O. Strandberg, C. M. Canali, A. H. MacDonald
We determine the effective total spin of local moments formed from acceptor states bound to Mn ions in GaAs by evaluating their magnetic Chern numbers. We find that when indivi…
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
T. O. Strandberg, C. M. Canali, A. H. MacDonald
Motivated by recent STM experiments, we present a theoretical study of the electronic and magnetic properties of the Mn-induced acceptor level obtained by substituting a single Ga…
Transition-metal dimers and physical limits on magnetic anisotropy
Tor O. Strandberg, Carlo. M. Canali, Allan H. MacDonald
Recent advances in nanoscience have raised interest in the minimum bit size required for classical information storage, i.e. for bistability with suppressed quantum tunnelling and…
Magnetic Anisotropy of Isolated Cobalt Nanoplatelets
T. O. Strandberg, C. M. Canali, A. H. MacDonald
Motivated in part by experiments performed by M.H. Pan et al. (nanoletters, v.5, p 83, 2005), we have undertaken a theoretical study of the the magnetic properties of two-monolayer…
