Energy Barriers for Thermally Activated Magnetization Reversal in Perpendicularly Magnetized Nanodisks in a Transverse Field
Corrado Carlo Maria Capriata, Bengt Gunnar Malm, Andrew D. Kent +1
Thermally-induced transitions between bistable magnetic states of magnetic tunnel junctions (MTJ) are of interest for generating random bitstreams and for applications in stochasti…
Thermally Activated Transitions Between Micromagnetic States
Gabriel D. Chaves-O'Flynn, D. L. Stein
We review work by the authors on thermal activation in nanoscopic magnetic systems. These systems present unique difficulties in analyzing noise-induced escape over a barrier, incl…
Thermal Activation Barriers for Creation and Annihilation of Magnetic Droplet Solitons in the Presence of Spin Transfer Torque
Gabriel D. Chaves-O'Flynn, Daniel L. Stein
We study noise-induced creation and annihilation of magnetic droplet solitons in experimental parameter regions in which they are linearly stable against drift. Exploiting the rota…
Magnetic domains without domain walls: a unique effect of He+ ion bombardment in ferrimagnetic Co/Tb multilayers
Łukasz Frąckowiak, Piotr Kuświk, Gabriel David Chaves-O'Flynn +6
We show that it is possible to engineer magnetic multi-domain configurations without domain walls in a prototypical rare earth/transition metal ferrimagnet using keV He+ ion bombar…
A Micromagnetic Study of Magnetization Reversal in Ferromagnetic Nanorings
Gabriel D. Chaves-O'Flynn, Andrew D. Kent, Daniel L. Stein
We present results of micromagnetic simulations of thin ferromagnetic rings undergoing magnetization reversal. This geometry is one of few examples in micromagnetics in which the t…
Micromagnetic Simulations of Ferromagnetic Rings
Gabriel D. Chaves-O'Flynn, Ke Xiao, D. L. Stein +1
Thin nanomagnetic rings have generated interest for fundamental studies of magnetization reversal and also for their potential in various applications, particularly as magnetic mem…
