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…
Proposal for a nanoscale variable resistor/electromechanical transistor
J. Bürki, C. A. Stafford, D. L. Stein
A nanoscale variable resistor consisting of a metal nanowire (active element), a dielectric, and a gate, is proposed. By means of the gate voltage, stochastic transitions between d…
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…
Comment on "Nonlinear current-voltage curves of gold quantum point contacts" [Appl. Phys. Lett. 87, 103104 (2005)]
J. Bürki, C. A. Stafford, D. L. Stein
In a recent Letter [Appl. Phys. Lett. 87, 103104 (2005)], Yoshida et al. report that nonlinearities in current-voltage curves of gold quantum point contacts occur as a result of a…
Magnetic Reversal in Nanoscopic Ferromagnetic Rings
Kirsten Martens, D. L. Stein, A. D. Kent
We present a theory of magnetization reversal due to thermal fluctuations in thin submicron-scale rings composed of soft magnetic materials. The magnetization in such geometries is…
Fluctuational Instabilities of Alkali and Noble Metal Nanowires
J. Bürki, C. A. Stafford, D. L. Stein
We introduce a continuum approach to studying the lifetimes of monovalent metal nanowires. By modelling the thermal fluctuations of cylindrical nanowires through the use of stochas…
