Enhanced annealing effect in an oxygen atmosphere on GaMnAs
M. Malfait, J. Vanacken, W. Van Roy +2
We report on in-situ resistivity measurements on GaMnAs during post-growth annealing in different atmospheres. A drop in the resistivity is observed when the GaMnAs is exposed to o…

Pulsed field studies of the magnetization reversal in molecular nanomagnets
J. Vanacken, S. Stroobants, M. Malfait +6
We report experimental studies of crystals of Mn12 molecular magnetic clusters in pulsed magnetic fields with sweep rates up to 4x10^3 T/s. The steps in the magnetization curve are…
