Magnetoelastic coupling in BaTiO3-based multiferroic structures
C. A. F. Vaz
Analytical expressions for the magnetoelastic anisotropy constants of cubic magnetic systems are derived for rectangular and oblique distortions originating from epitaxial growth o…
Energy equilibriation processes of electrons, magnons and phonons on the femtosecond timescale
J. Walowski, G. Müller, M. Djordjevic +4
By means of time-resolved Kerr spectroscopy experiments we relate the energy dissipation processes on the femtosecond (electron-spin relaxation time ) and nanosecond tim…
Direct observation of domain-wall configurations transformed by spin currents
M. Klaui, P. -O. Jubert, R. Allenspach +7
Direct observations of current-induced domain-wall propagation by spin-polarized scanning electron microscopy are reported. Current pulses move head-to-head as well as tail-to-tail…
Bubble domains in disc-shaped ferromagnetic particles
S. Komineas, C. A. F. Vaz, J. A. C. Bland +1
We study the fundamental magnetic states of disc-shaped ferromagnetic particles with a uniaxial anisotropy along the symmetry axis. Besides the monodomain, a bidomain state is also…
