Autor: Davis, J. P., Vick, D., Burgess, J. A. J., Fortin, D. C., Li, P., Sauer, V., Hiebert, W. K., Freeman, M. R.

Publikováno v: J P Davis et al 2010 New J. Phys. 12 093033

We demonstrate that the transition from the high-field state to the vortex state in a nanomagnetic disk shows the magnetic equivalent of supercooling. This is evidence that this magnetic transition can be described in terms of a modified Landau first

Nano-Torsional Resonator Torque Magnetometry

Autor: Davis, J. P., Vick, D., Fortin, D. C., Burgess, J. A. J., Hiebert, W. K., Freeman, M. R.

Publikováno v: Appl. Phys. Lett. 96, 072513 (2010).

Magnetic torque is used to actuate nano-torsional resonators, which are fabricated by focused-ion-beam milling of permalloy coated silicon nitride membranes. Optical interferometry is used to measure the mechanical response of two torsion modes at re

Report

Spatially resolved ultrafast precessional magnetization reversal

Autor: Hiebert, W. K., Lagae, L., De Boeck, J.

Publikováno v: Phys. Rev. B 68, 020402(R), 2003

Spatially resolved measurements of quasi-ballistic precessional magnetic switching in a microstructure are presented. Crossing current wires allow detailed study of the precessional switching induced by coincident longitudinal and transverse magnetic
