摘要:

Landau--Lifshitz--Baryakhtar (LLBar)方程是Landau--Lifshitz--Gilbert方程和Landau--Lifshitz--Bloch方程的推广,它考虑了非局部阻尼的贡献,并在低于Curie温度的中等温度下有效。因此,它被用于解释在磁子学和磁畴壁动力学的各种问题中实验观测与已知理论之间的差异。本文证明了LLBar方程全局弱解、强解和正则解的存在性与唯一性,并讨论了解的Hölder连续性。

英文摘要:

The Landau--Lifshitz--Baryakhtar (LLBar) equation is a generalisation of the Landau--Lifshitz--Gilbert and the Landau--Lifshitz--Bloch equations which takes into account contributions from nonlocal damping and is valid at moderate temperature below the Curie temperature. Therefore, it is used to explain some discrepancies between the experimental observations and the known theories in various problems on magnonics and magnetic domain-wall dynamics. In this paper, the existence and uniqueness of global weak, strong, and regular solutions to LLBar equation are proven. Hölder continuity of the solution is also discussed.
