Imaging small-amplitude magnetization dynamics in a longitudinally magnetized microwire
We have used time-resolved scanning Kerr microscopy to study spin waves in a magnetic microwire subjected to a bias magnetic field applied parallel to its long axis. The spin-wave spectra obtained from different points near one end of the wire reveal several normal modes. We found that modes of a higher frequency occupied regions located further from the end of the wire. This was interpreted in...
متن کاملSlow magnetization dynamics of small permalloy islands
The conditions that lead to specific domain configurations and the associated switching characteristics of small permalloy islands were studied by using magnetic force microscopy. By measuring a large number of particles, it was established that islands that have nonzero remanent moments ~nonsolenoidal! exist in one of three distinct configurations, namely: ~a! true single domain, ~b! quasising...
متن کاملDynamics In Magnetized Interstellar Gas
Interstellar medium is turbulent and this induces relative motions of dust grains. We calculate relative velocities of charged grains in a partially ionized magnetized gas. We account for anisotropy of magnetohydrodynamic (MHD) turbulence, grain coupling with magnetic field, and the turbulence cutoff arising from the ambipolar drag. We obtain grain velocities for turbulence with parameters cons...
متن کاملSmall-tunneling-amplitude boson-Hubbard dimer. II. Dynamics
We present analytical relations for the quantum evolution of the number difference of bosons between the two sites of a double-well potential, by using perturbative results for small tunneling amplitudes in the twomode approximation. Results are obtained for two different initial conditions: completely localized states and coherent spin states. In the former case both the short and the long tim...
