就是想请问各位大大superconductivity分成两型
type 1 have the addition property of expelling all magnetic flux
when could below the critical temperature.This is called
Meissner effect.
type 2 have a more complicate field dependence.Below a given critical
critical temperature,they exclude the magnetic field completely.
以上看完之後,是不是两型的区分是在临界温度之下有无电磁场呢?
