Orbital and spin contributions to the -tensors in metal nanoparticles
A. Cehovin, C. M. Canali, A. H. MacDonald
We present a theoretical study of the mesoscopic fluctuations of -tensors in a metal nanoparticle. The calculations were performed using a semi-realistic tight-binding model, wh…
Elementary Excitations of Ferromagnetic Metal Nanoparticles
A. Cehovin, C. M. Canali, A. H. MacDonald
We present a theory of the elementary spin excitations in transition metal ferromagnet nanoparticles which achieves a unified and consistent quantum description of both collective…
Chern Numbers for Spin Models of Transition Metal Nanomagnets
C. M. Canali, A. Cehovin, A. H. MacDonald
We argue 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 f…
Magnetization orientation dependence of the quasiparticle spectrum and hysteresis in ferromagnetic metal nanoparticles
A. Cehovin, C. M. Canali, A. H. MacDonald
We use a microscopic Slater-Koster tight-binding model with short-range exchange and atomic spin-orbit interactions that realistically captures generic features of ferromagnetic me…
