Reply on ``Fluctuation-dissipation considerations for phenomenological damping models for ferromagnetic thin films'' [N. Smith, J. Appl. Phys. \bf{92}, 3877 (2002)]
Vladimir L. Safonov, H. Neal Bertram
We show that the critique of our recent papers presented in the abovementioned paper (NS) appeals to an incorrect mathematical analogy between electrical circuits and linear magnet…
Microscopic relaxation mechanisms and linear magnetization dynamics
Vladimir L. Safonov, H. Neal Bertram
Linear magnetization dynamics in the presense of a thermal bath is analyzed for two general classes of microscopic damping mechanisms. The resulting stochastic differential equatio…
Continuous Unitary Transformations
Vladimir L. Safonov
In the present time we observe a growing number of publications where the, so-called, flow equations are successfully used to diagonalize Hamiltonians by means of an appropriate un…
Thermal magnetization fluctuations in thin films and a new physical form for magnetization damping
Vladimir L. Safonov, H. Neal Bertram
The effect of thermal fluctuations on a thin film magnetoresistive element has been calculated. The technique involves adding to the basic spin dynamics a general form of interacti…
A single mode realization of SU(1,1)
Vladimir L. Safonov
A single mode realization of SU(1,1) algebra is proposed. This realization makes it possible to reduce the problem of two nonlinear interacting oscillators to the problem of free m…
Magnetization reversal in a "quasi" single domain magnetic grain: a new numerical micromagnetic technique
Vladimir L. Safonov, H. Neal Bertram
Magnetization reversal in a fine ferromagnetic grain is simulated for the case of an instantaneously applied reversal magnetic field. The Hamiltonian of the system contains the exc…
