    Microscopic theory for coupled atomistic magnetization and lattice dynamics 
    Fransson, J.; Thonig, D.; Bessarab, Pavel; Bhattacharjee, S.; Hellsvik, J.; Nordström, L. (American Physical Society (APS), 2017-12-13)
    A coupled atomistic spin and lattice dynamics approach is developed which merges the dynamics of these two degrees of freedom into a single set of coupled equations of motion. The underlying microscopic model comprises local exchange interactions between ...

    Theory of noncollinear interactions beyond Heisenberg exchange: Applications to bcc Fe 
    Szilva, A.; Thonig, D.; Bessarab, Pavel; Kvashnin, Y. O.; Rodrigues, D. C. M.; Cardias, R.; Pereiro, M.; Nordström, L.; Bergman, A.; Klautau, A. B.; Eriksson, O. (American Physical Society (APS), 2017-10-10)
    We show for a simple noncollinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise energy variation computed in terms of multiple-scattering formalism ...
