摘要

摘要 我们提出了一种反向散射变换方法的特殊变体,用于构建和分析半无限样品易轴铁磁体表面部分钉住自旋的情况下的孤子激发。我们考虑了自由边缘自旋和自旋完全钉在样品边界的极限情况。我们发现了在样品表面附近定位的孤子的频率和调制特性。在边缘自旋钉合程度不同的情况下,我们研究了移动孤子的核心因其从样品边界的弹性反射而发生的变化。我们获得了控制半无限样品中磁孤子动力学的运动积分。

Solitons in a semi-infinite ferromagnet with anisotropy of the  easy axis type

Solitons in a semi-infinite ferromagnet with anisotropy of the easy axis type

We propose a special variant of the inverse scattering transform method to construct and analyze soliton excitations in a semi-infinite sample of an easy-axis ferromagnet in the case of a partial pinning of spins at its surface. We consider the limit cases of free edge spins and spins that are fully pinned at the sample boundary. We find frequency and modulation characteristics of solitons localized near the sample surface. In the case of different degrees of edge spin pinning, we study changes in the cores of moving solitons as a result of their elastic reflection from the sample boundary. We obtain integrals of motion that control the dynamics of magnetic solitons in a semi-infinite sample.
