Results of low-temperature upper critical field measurements for Nd2–xCexCuO4+δ single crystals with various x and nonstoichiometric disorder (δ) are presented. The coherence length of pair correlation ξ and the product kFξ , where kF is the Fermi wave vector, are estimated. It is shown that for investigated single crystals parameter kFξ @ 100 and thus phenomenologically NdCeCuO-system is in a range of Cooper-pair-based (BCS) superconductivity.
