...This means that superconductors exhibit perfect diamagnetism in the classification of magnetism. It was discovered in 1933 by German Fritz Walther Meissner (1882-1974) and R. Ochsenfeld, and a qualitative explanation was given in 1935 by the London brothers, and a microscopic explanation was given in 1957 by J. Bardeen, L. Cooper, and JR Schrieffer. This phenomenon occurs because the wave function of the electron pairs responsible for superconductivity is difficult to change in response to magnetic fields, and it is the superconducting current that continues to flow several hundred to several thousand angstroms from the surface of the superconductor that eliminates the magnetic field. ... *Some of the terminology references "Meissner, FW" are listed below.

…これは超伝導体が,磁性の分類でいうと完全反磁性を示すことを意味している。1933年にドイツのマイスナーFritz Walther Meissner(1882‐1974)とR.オクセンフェルトによって発見され,定性的な説明は35年ロンドン兄弟によって,また微視的な説明は57年J.バーディーン,L.クーパー,J.R.シュリーファーによって与えられた。超伝導をになう電子対の波動関数が磁場に対して変化しにくいことに基づいて生ずる現象で,磁場を排除しているのは超伝導体の表面の数百~数千Åのところを流れ続ける超伝導電流である。… ※「Meissner,F.W.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
