Quantum annealing by ferromagnetic interaction with the mean-field scheme

Suzuki, Sei; Nishimori, Hidetoshi - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 1, pp. 137-140

of quantum annealing over simulated annealing. We consider the ferromagnetic interaction as a source of quantum … fluctuations. Using the mean-field annealing scheme, we show that quantum annealing by ferromagnetic interaction is more efficient …

X-ray detected ferromagnetic resonance in thin films

Goulon, J.; Rogalev, A.; Wilhelm, F.; Jaouen, N.; … - In: The European Physical Journal B - Condensed Matter and … 53 (2006) 2, pp. 169-184

We discuss the physical content of X-ray Detected Magnetic Resonance (XDMR), i.e. a novel spectroscopy which uses XMCD to probe the resonant precession of the local magnetization in a strong microwave pump field. We focus on the simplest case of a steady-state precession of elemental moments in...

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...
