Irreversibility temperature in superconductors

Click For Summary
SUMMARY

The irreversibility temperature in type II superconductors, such as MgB2, is a critical point where the flux lattice formation occurs, leading to observable changes in NMR lineshape. This temperature is distinct from the field-corrected critical temperature (Tc) and is essential for understanding the behavior of superconductors under varying magnetic fields. The discussion emphasizes the importance of referencing experimental results to support findings related to this phenomenon.

Hello, I would be grateful is someone could explain what the irreversibly temperature in type II superconductors is.

I have just done some NMR experiments on MgB2 and get a lineshape change at the the irreversibility temperature as opposed to the field corrected Tc, so I believe it has something to do with the flux lattice formation.

Regards,

Peter
