Comment on ""Proximity effect in ultrafin Pb/Ag multilayers within the Cooper limit"

TL;DR

This paper critically evaluates a recent study on the proximity effect in ultrathin Pb/Ag multilayers, arguing that its data interpretation is unreliable and neglects significant prior research.

Contribution

It provides a critical commentary highlighting flaws in the interpretation and overlooks of existing literature in the recent study.

Findings

The interpretation of the data in cond-mat/0302251 is questionable.

Previous relevant work was ignored in the original paper.

The critique emphasizes the need for careful analysis in proximity effect studies.

Abstract

I present here critical comment to the recent e-print "Proximity effect in ultrafin Pb/Ag multilayers within the Cooper limit" by by O.Bourgeois, A.Frydman and R.C.Dynes, demonstrating that the interpretaion of the data presented in cond-mat/0302251 does not seem to be reliable, and, simulteneously, large amount of previous work was ignored.
