迈斯纳效应、抗磁性和classical physics
Meissner effect, diamagnetism, and classical physics - a review
摘要:
我们回顾了经典物理学关于迈斯纳效应和伦敦方程的文献。我们首先讨论玻尔-范列文定理与超导体完全抗磁性的相关性。结论是,该定理是基于假设是无效的。我们还指出文献中的结果,证明从冷却到超导的样品中排出的磁通量可以简单地理解为接近静磁能极小值。这些结果已经发表了好几次,但仍然有许多关于磁学的教科书声称不存在经典的抗磁性,几乎所有关于超导性的书籍都重复了迈斯纳1933年的声明,即通量驱逐没有经典的解释。
英文摘要:
We review the literature on what classical physics has to say about the Meissner effect and the London equations. We first discuss the relevance of the Bohr-van Leeuwen theorem for the perfect diamagnetism of superconductors. The conclusion is that the theorem is based on assumptions that are not valid. We also point out results in the literature which prove that the magnetic flux expulsion from a sample cooled to superconductivity can be simply understood as an approach to the magnetostatic energy minimum. These results have been published several times but still many textbooks on magnetism claim that there is no classical diamagnetism, and virtually all books on superconductivity repeat Meissner's 1933 statement that flux expulsion has no classical explanation.
