摘要
固体物理学是物理学本科教育的一门核心课程,其内容紧密联系凝聚态物理研究前沿.在教学中引入适当的前沿进展,可以拓展学生的学术视野,激发深入学习和参与研究的动力.本文结合固体物理中的铁磁性章节,选择铁磁金属中磁畴壁导致的电阻作为一个典型案例,引导学生整合能带论、微扰论和输运现象等基础知识,分析磁畴壁中的自旋相关输运问题,从而将自旋电子学的前沿研究融入固体物理教学中,为打造具有高阶性、创新性和挑战度的固体物理课程提供参考.
Solid state physics is an important course for undergraduate students of physics,and its contents are closely related to the research frontiers of condensed matter physics.Introducing appropriate latest progress in the teaching can expand students’scientific level and encourage them to pursue further studies and researches.In this paper,domain-wall resistance in ferromagnetic metals in the chapter of magnetism in solid states is taken as a typical example and a guidance for students is provided to analyze the spin dependent transport in magnetic domain walls.In this process,the students need to integrate the knowledge they have learned including the energy band theory,perturbation theory and transport phenomena in quantum mechanics and solid state physics.By systematically illustrating this typical example,the integration of the cutting-edge research of spintronics into teaching solid state physics is demonstrated which would be a useful reference for creating a high-level,innovative and challenging course of solid state physics.
