期刊Influence of magnetostatic interaction on the magnetization reversal of patterned Co/Pd multilayers nanorings
《IEEE Transactions on Magnetics》Ren, Yang[1,2]; Liu, Xinming M.[1]; Singh, N.[2]; Adeyeye, A.O.[1]
We present a systematical investigation of magnetostatic interaction on magnetization reversal process for [Co(5A)/Pd(30A)]n multilayers nanoring arrays separated by various edge-to-edge interring spacing (s). We obse...显示全部

期刊Vortex chirality in exchange-biased elliptical magnetic rings
《Physical Review Letters》Jung, W; Castano, FJ; Ross, CA
The flux-closed or "vortex" state in thin-film magnetic rings has beenproposed as a data storage token, but it has proven difficult to control the vortex chirality in asimple manner. Here, a model is describ...显示全部

期刊The role of dipolar interactions for the magnetic properties of ferromagnetic nanoring
《Journal of Magnetism and Magnetic Materials》Li, Y.[1]; Wang, T.X.[2]
We investigate numerically the effects of the dipolar interactions on magnetic properties in small ferromagnetic nanorings using a Monte Carlo technique. Our simulated results show that the strength of dipolar interac...显示全部
