Softening of spin-wave stiffness near the ferromagnetic phase transition in diluted magnetic semiconductors

Sun, Shih-Jye; Lin, Hsiu-Hau - In: The European Physical Journal B - Condensed Matter and … 49 (2006) 4, pp. 403-406

Employing the self-consistent Green's function approach, we studied the temperature dependence of the spin-wave stiffness in diluted magnetic semiconductors. Note that the Green's function approach includes the spatial and temperature fluctuations simultaneously which was not possible within...

MAGNONS HEAT TRANSPORT AT AN INTEGRATED NANOSTRUCTURE IN ULTRATHIN HEISENBERG FERROMAGNETIC FILMS

BELHADI, MEHAND; KHEFFACHE, SEDIK - In: Surface Review and Letters (SRL) 18 (2011) 06, pp. 241-248

A theoretical model is presented for the study of magnons heat transfer across an integrated nanostructure acting as interface material between two ultrathin Heisenberg ferromagnetic films. This is done by calculating the transmission rates of the spin wave modes through the consideration of the...
