Abstract

Results of low-temperature upper critical field measurements for Nd $_{2 - x}$ Ce $_{x}$ CuO $_{4 + δ}$ single crystals with various $x$ and nonstoichiometric disorder ( $δ$ ) are presented. The coherence length of pair correlation $ξ$ and the product $k_{F}$ $ξ$ , where $k_{F}$ is the Fermi wave vector, are estimated. It is shown that for investigated single crystals parameter $k_{F}$ $ξ$ $≅$ 100 and thus phenomenologically NdCeCuO - system is in a range of Cooper-pair-based (BCS) superconductivity.
