Uniaxial strain induced band splitting in semiconducting SrTiO3
Young Jun Chang,Young Jun Chang,Young Jun Chang,Guru Khalsa,Luca Moreschini,Andrew L. Walter,Andrew L. Walter,Aaron Bostwick,Karsten Horn,Allan H. MacDonald,Eli Rotenberg +10 more
TL;DR: In this paper, angle-resolved photoemission spectroscopy was used to study the influence of mechanically induced uniaxial strain on the electronic structure of the oxide semiconductor SrTiO${}_{3}$.
Magnetic interactions of substitutional Mn pairs in GaAs
TL;DR: In this article, a kinetic exchange tight-binding model was employed to calculate the magnetic interaction and anisotropy energies of a pair of substitutional Mn atoms in GaAs as a function of their separation distanc

Pair potentials and the bonding energy of d-band metals
Allan H. MacDonald,Roger Taylor +1 more
TL;DR: In this paper, a method for decomposing the bonding energy of d-band metals into a sum of pairwise interactions between transition metal ions is presented, and the dependence of these pair potentials on the configuration of the ions is examined by evaluating them for several model dband perfect crystals.

Chern Numbers for Spin Models of Transition Metal Nanomagnets
TL;DR: It is argued that ferromagnetic transition metal nanoparticles with fewer than approximately 100 atoms can be described by an effective Hamiltonian with a single giant spin degree of freedom.
