| 中文摘要 | Magnetization reversal process and magnetic relaxation of Fe3Pt nanowire arrays fabricated by electrodeposition have been investigated by means of micromagnetic simulation and magnetization measurements. Time dependence of magnetization reveals that the nanowire arrays exhibit a strong magnetic viscosity effect. The magnetic viscosity coefficients S, which are dependent on temperature and magnetic field, achieve maximum values near the coercivity. The activation volume V-*, defined as the effective volume involved in the magnetization reversal process, increases with temperature as T-1/2 and linearly with the diameter, which is consistent with the theoretical prediction of the thermally activated magnetization reversal process. |
