Dr. Thiele studies the physics of ferromagnetic domain walls at the micromagnetic level. The work is intended to advance the understanding of processes that occur in magnetic recording.
Current work is theoretical, ranging from pure analytic to massive computer simulations.
Particular emphases are on the connection of domain topology and dynamics, and the role of the statistical excitation of spin waves. The increased accessibility of computer graphics provided by the advent of workstations has made possible a great increase in the sophistication of the graphical representation of vector fields. The use of mappings to the directional sphere in illustrating micromagnetic vector field topology has now been supplemented by three-dimensional color stereoscopic renderings of these fields. 4593-4595, April 1991. 2584-2586, March 1984.
