Upper critical field in electron-doped cuprate superconductor Nd${}_{2-x}$Ce${}_x$CuO${}_{4+\delta }$: two-gap model

T. B. Charikova, N. G. Shelushinina, G. I. Harus +3

We present resistivity measurements of the upper critical field (H${}_{c2}$) phase diagram as a function of temperature (T) for Nd${}_{1.85}$Ce${}_{0.15}$CuO${}_{4+\delta }$/SrTiO${}_3$ single cry…
