The estimation of coherence length for electron-doped superconductor NdCeCuO
Results of low-temperature upper critical field measurements for
NdCeCuO single crystals with various and
nonstoichiometric disorder () are presented. The coherence length of
pair correlation and the product , where is the Fermi
wave vector, are estimated. It is shown that for investigated single crystals
parameter 100 and thus phenomenologically NdCeCuO - system
is in a range of Cooper-pair-based (BCS) superconductivity.Comment: 8 pages, 3 figures, 2 table
