The emerging Ni-based superconducting oxide thin films are rather intriguing to the entire condensed matter physics.Here,we report some brief experimental results on transport measurements for a 14-nm-thick superconducting Nd0.8Sr0.2NiO2/SrTiO3 thin-film heterostructure with an onset transition temperature of~9.5 K.Photoluminescence measurements reveal that there is negligible oxygen vacancy creation in the SrTiO3 substrate during thin-film deposition and post chemical reduction for the Nd0.8Sr0.2NiO2/SrTiO3 heterostructure.It was found that the critical current density of the Nd0.8Sr0.2NiO2/SrTiO3 thin-film heterostructure is rela-tively small,~4×103 A·cm-2.Although the surface steps of SrTiO3 substrates lead to an anisotropy for in-plane resistivity,the superconducting transition temperatures are almost the same.The out-of-plane magnetotransport mea-surements yield an upper critical field of~11.4 T and an estimated in-plane Ginzburg-Landau coherence length of~5.4 nm.High-field magnetotransport measurements up to 50 T reveal anisotropic critical fields at 1.8 K for three different measurement geometries and a complicated Hall effect.An electric field applied via the SrTiO3 sub-strate slightly varies the superconducting transition temperature.These experimental results could be useful for this rapidly developing field.
