Three- and four-µm-thick YBa2Cu3O7 layers with high critical-current densities on flexible metallic substrates by the BaF2 process
We report on the synthesis and performance of 3- and 4-µm-thick YBa2Cu3O7 films on buffered metallic tapes. The precursor films were deposited by vacuum coevaporation of BaF2, Y, and Cu on the s...

Interface effects in highly oriented films of the Heusler alloy Co2MnSi on GaAs(001)
Highly (001) oriented thin films of Co2MnSi have been grown on lattice-matched GaAs(001) without a buffer layer. Stoichiometric films grown at the highest substrate temperature of 689 K showed the low...

We investigate the minimal field strength in precessional magnetization switching using the Landau-Lifshitz-Gilbert equation in undercritically damped systems. It is shown that precessional switching occurs when localized trajectories in phase space become unlocalized upon application of field pulses. By studying the evolution of the phase space, we obtain the analytical expression of the critical switching field in the limit of small damping for a magnetic object with biaxial anisotropy in both the easy and hard plane. We also calculate the switching times for the zero damping situation by numerical means. We show that applying the field along the medium axis is good for both small field and fast switching times. ©2006 American Institute of Physics
