Magnetization dynamics of two interacting spins in an external magnetic field
COFFEY, WILLIAM THOMAS; KALYMYKOV, YURI PETROVICH; TITOV, SERGEY (American Physical Society, 2005)The longitudinal relaxation time of the magnetization of a system of two exchange coupled spins subjected to a strong magnetic field is calculated exactly by averaging the stochastic Gilbert-Landau-Lifshitz equation for ... -
Thermally activated escape rate for the Brownian motion of a fixed axis rotator in an asymmetrical double-well potential for all values of the dissipation
COFFEY, WILLIAM THOMAS; KALYMYKOV, YURI PETROVICH; TITOV, SERGEY (American Institute of Physics, 2005)The Kramers theory of the escape rate of a Brownian particle from a potential well as extended by Mel'nikov and Meshkov, [J. Chem. Phys. 85, 1018 (1986)] is used to evaluate the relaxation times and the dynamic susceptibility ...
