Thermal fluctuations and longitudinal relaxation of single-domain magnetic particles at elevated temperatures
D. A. Garanin, O. Chubykalo-Fesenko
We present numerical and analytical results for the swiching times of magnetic nanoparticles with uniaxial anisotropy at elevated temperatures, including the vicinity of T_c. The c…
Comment on cond-mat/0406502 by V. Yukalov and E. Yukalova on Coherent Nuclear Radiation
E. M. Chudnovsky, D. A. Garanin
We show that the argument of Yukalov and Yukalova that dipole-dipole interaction prevents a system of magnetic dipoles from exhibiting superradiance unless assisted by a resonator…
Interference effect in the Landau-Zener tunneling of the antiferromagnetically coupled dimer of single-molecule magnets
D. A. Garanin
Two antiferromagnetically coupled tunneling systems is a minimal model exhibiting the effect of quantum-mechanical phase in the Landau-Zener effect. It is shown that the averaged s…
Nonlinear response of superparamagnets with finite damping: an analytical approach
J. L. Garcia-Palacios, D. A. Garanin
The strongly damping-dependent nonlinear dynamical response of classical superparamagnets is investigated by means of an analytical approach. Using rigorous balance equations for t…
Phonon superradiance and phonon laser effect in nanomagnets
E. M. Chudnovsky, D. A. Garanin
We show that the theory of spin-phonon processes in paramagnetic solids must take into account the coherent generation of phonons by the magnetic centers. This effect should drasti…
Transitions at avoided level crossing with interaction and disorder
D. A. Garanin, R. Schilling
We investigate the influence of interaction between tunneling particles and disorder on their avoided-level-crossing transitions in the fast-sweep limit. Whereas the results confir…
