Time-resolved imaging of spin transfer switching: Beyond the macrospin concept (2006)
Acremann, Y, Strachan, J. P., Chembrolu, V, Andrews, S. D., Tyliszczak, T, Katine, J. A., ...
Time-resolved images of the magnetization switching process in a spin transfer structure, obtained by ultrafast x-ray microscopy, reveal the limitations of the macrospin model. Instead of a coherent...
Pulsed precessional motion on the 'back of an envelope' (2003)
Buess, Matthias, Acremann, Y., Kashuba, A., Back, Christian, Pescia, D.
In a recent paper (Acremann et al 2000 Science 290 492) the precessional trajectory of the magnetization vector was imaged with spatial resolution as a function of the time elapsed after a magnetic...
Magnetic Spatial Non-Uniformities on the Picosecond Timescale (2002)
Acremann, Y., Kashuba, A., Buess, Matthias, Pescia, D., Back, Christian
The magnetization of a Co disk with an in-plane flux-closure domain structure was subject to a picosecond magnetic field pulse perpendicular to the plane. Images with sub-micron spatial resolution...
Ultrafast Generation of Magnetic Fields in a Schottky Diode (2001)
Acremann, Y., Buess, Matthias, Back, Christian, Dumm, Martin, Bayreuther, Günther, Pescia, D.
For the development of future magnetic data storage technologies, the ultrafast generation of local magnetic fields is essential. Subnanosecond excitation of the magnetic state has so far been...
Bifurcation in Precessional Switching (2001)
Acremann, Y., Back, Christian, Buess, M., Pescia, D., Pokrovsky, V.
Acremann, Y., Heinzel, T., Gini, K. Ensslin E., Melchior, H., Holland, M.
The equilibration length between spin-polarized edge states in the Quantum Hall regime is measured as a function of a gate voltage applied to an electrode on top of the edge channels. Reproducible...
