研究了电场对Pt/Co体系磁畴结构的影响。的迷宫域的宽度显着修改的EF在略低于居里温度的温度下的应用。经过详细的分析，在微观交换刚度的变化引起的EF应用建议占主导地位的调制的畴宽度在实验中观察到的。电子在Co层表面的积累导致微观交换刚度和居里温度的增加。这一结果与最近的理论预测相一致。出版社：AIP Publishing
The electric field (EF) effect on the magnetic domain structure of a Pt/Co system was studied, where an EF was applied to the top surface of the Co layer. The width of the maze domain was significantly modified by the application of the EF at a temperature slightly below the Curie temperature. After a detailed analysis, a change in the microscopic exchange stiffness induced by the EF application was suggested to dominate the modulation of the domain width observed in the experiment. The accumulation of electrons at the surface of the Co layer resulted in an increase in the microscopic exchange stiffness and the Curie temperature. The result was consistent with the recent theoretical prediction. Published by AIP Publishing.
