【摘要】 磁畴是磁性材料中的基础结构，它决定了材料的磁学性质。通过深入研究磁畴，我们可以深入理解磁性材料的特性，优化其性能，进而推动相关应用的进步。洛伦兹电镜，作为一种基于透射电镜的设备，能够观察和分析磁性材料的磁畴结构。其工作原理是利用洛伦兹力使电子束发生偏转，形成明暗相间的图案，从而反映出面内磁矩的不同取向。洛伦兹电镜具有超高的探测灵敏度，其分辨率能够达到纳米量级，因此被广泛应用于磁性材料的研究。将洛伦兹电镜引入本科教学是非常有意义的。通过实际操作，学生可以更好地掌握科学研究的实践技能和方法。同时，学生还能够培养科研素养和科研能力，为他们未来的科研工作打下坚实的基础。因此，将洛伦兹电镜应用于本科教学不仅是可行的，而且是必要的。更多还原

【Abstract】 The magnetic domain is the fundamental structure in magnetic materials, which dictates their magnetic properties.By conducting in-depth investigations into magnetic domains, we can enhance our understanding of the characteristics of magnetic materials, optimize their performance, and further advance related applications.The Lorentz transmission Electron Microscope(LTEM),as a device based on transmission electron microscopy, enables the observation and analysis of the magnetic domain structures of these materials.Its operational principle relies on utilizing the Lorentz force to deflect the electron beam, resulting in patterns with alternating brightness that reflect different orientations of magnetic moments within the plane.With its ultrahigh detection sensitivity and nanometer-level resolution, LTEM finds extensive application in studying magnetic materials.Introducing LTEM into undergraduate teaching holds significant importance as it allows students to gain practical skills and research methods through hands-on experience.Simultaneously, it cultivates scientific research literacy and capabilities among students while laying a solid foundation for their future scientific endeavors.Therefore, applying LTEM in undergraduate teaching is not only feasible but also necessary.更多还原
