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 inv...
