Thermal stability of coupled ferromagnetic and superparamagnetic particles
Vladimir L. Safonov, H. Neal Bertram
We consider a single-domain ferromagnetic particle with uniaxial anisotropy coupled to a single-domain soft ferromagnetic particle (superparamagnetic particle). The problem of ther…
Nonlinear microscopic relaxation of uniform magnetization precession
Vladimir L. Safonov, H. Neal Bertram
Dynamic relaxation for nonlinear magnetization excitation is analyzed. For direct processes, such as magnon-electron scattering and two-magnon scattering, the relaxation rate is de…
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…
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…
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…
