Noise-induced effects in magnetization reversal and chirality control of circular array of single-domained nanomagnets

Autor: Pankratov, A. L., Vdovichev, S. N., Nefedov, I. M., Karetnikova, I. R.

The effect of noise on the process of high-speed remagnetization of vortex state of a pentagonal array of five circular magnetic nanoparticles is studied by means of computer simulation of Landau-Lifshits model. The mean switching time and its standa

Publikováno v: Phys. Rev. B v.71, p. 094416 (2005)

Using numerical simulation we have studied a magnetization distribution and a process of magnetization reversal in nanoscale magnets placed above a superconductor plane. In order to consider an influence of superconductor on magnetization distributio

Report

Interacting circular nanomagnets

Autor: Fraerman, A. A., Gusev, S. A., Mazo, L. A., Nefedov, I. M., Nozdrin, Yu. N., Karetnikova, I. R., Sapozhnikov, M. V., Shereshevsky, I. A., Suhodoev, L. V.

Regular 2D rectangular lattices of permalloy nanoparticles (40 nm in diameter) were prepared by the method of the electron lithography. The magnetization curves were studied by Hall magnetometry with the compensation technique for different external
