Abstract The electric-field induced modifications of the symmetric and asymmetric exchange stiffness constants for the prototypical transition-metal system of a Co monolayer on Pt(111) are determined from first-principles calculated total energy differences of spin-spiral states with oppositely rotating magnetizations in the presence of both the external field and spin–orbit coupling. The trend underlying the modifications is shown to be linked to orbital magnetism. The results demonstrate that an electric field may be a promising approach to manipulate macroscopically magnetic textures.

外电场中过渡金属薄膜界面的对称和非对称交换刚度

摘要 对于 Pt(111) 上 Co 单层的原型过渡金属系统的对称和非对称交换刚度常数的电场诱导修改是根据第一性原理计算的具有相反旋转磁化强度的自旋螺旋态的总能量差确定的。在存在外场和自旋轨道耦合的情况下。表明这些修改背后的趋势与轨道磁性有关。结果表明，电场可能是操纵宏观磁性结构的有前途的方法。
