摘要

结果表明，沉积在顺磁性或超导衬底上的铁磁薄膜的能量以Dzyaloshinskii-Moriya相互作用的形式有所贡献。这种贡献是由于铁磁薄膜的磁化与它在顺磁体或超导体中的超电流引起的磁化相互作用的结果，并导致手性简并的消除，自旋波的非互易性和手性态的形成，如磁性天子。我们的估计表明实验观察到预测效应的可能性。

Magnetostatic Mechanism of Chiral Symmetry Breaking in Multilayer Magnetic Structures

It is shown that the energy of a ferromagnetic film deposited onto a paramagnetic or superconducting substrate acquires a contribution in the form of the Dzyaloshinskii–Moriya interaction. This contribution appears as a result of the magnetostatic interaction of the magnetization of the ferromagnetic film with the magnetization induced by it in a paramagnet or by the supercurrent in the superconductor and leads to the removal of the chiral degeneracy, nonreciprocity of spin waves, and the formation of chiral states such as magnetic skyrmions. Our estimates indicate the possibility of experimental observation of predicted effects.
