摘要:

研究了在纳米多孔氧化铝膜上制备的不同孔径的有序纳米Co/Cu/Py多层反点膜的磁性。通过使用由Cu薄层分离的Co和Py膜,并调整NAMS的孔径,我们能够发挥膜的磁化率,并观察阶梯磁化曲线,作为Co和Py膜的不同磁化率的结果。多层反量子点的磁性能进行了测量,并与Cu/Py反量子点的结果进行了比较。通过微磁模拟研究了在每个单独的层和多层中发生的磁化反转过程。

英文摘要:

The magnetic properties of ordered nanoscale Co/Cu/Py multilayer antidot films with different pore sizes prepared on top of nanoporous alumina membranes are presented. By using Co and Py films separated by a Cu thin layer, and tuning the pore diameters of the NAMs we were able to play with the coercivity of the films and observe stepped magnetization curves, as a consequence of the different coercivities of the Co and Py films. The magnetic properties of the multilayer antidots have been measured and compared with results obtained for antidots of Cu/Py. The magnetization reversal process that occurs in each individual layer and in the multilayer was studied by means of micromagnetic simulations.
