Superconductivity in infinite-layer nickelates
Abstract
The recent discovery of the superconductivity in the doped infinite layer nickelates RNiO2 (R=La, Pr, Nd) is of great interest since the nickelates are isostructural to doped (Ca,Sr)CuO2 having superconducting transition temperature (T c) of about 110 K. Verifying the commonalities and differences between these oxides will certainly give a new insight into the mechanism of high T c superconductivity in correlated electron systems. In this paper, we review experimental and theoretical works on this new superconductor and discuss the future perspectives for the "nickel age" of superconductivity.
