Attenuation of a Magnetic Field by a Superconductor

Publisher's Note: Nonlocal effect and dimensions of Cooper pairs measured by low-energy muons and polarized neutrons in type-I superconductors [Phys. Rev. B87, 104508 (2013)]

“…However, the validity of this observation is questionable. 10 In a subsequent paper 11 the authors, as a matter of fact, discard this result mentioning that they failed to reproduce it with other 24 identically fabricated samples and by not providing new data points for the "good" sample.…”

In this technique a fixed-frequency microwave absorption is measured versus an external magnetic field applied parallel to the sample surface.…”
