The recent discovery of superconductivity in doped infinite layer nickelates RNiO2 is intriguing, as they are isostructural to doped (Ca, Sr)CuO2 which exhibit superconductivity at about 110 K. Investigating the similarities and differences between these oxides will provide new insights into the mechanism of high Tc superconductivity in correlated electron systems. This paper reviews experimental and theoretical works on the new superconductor and discusses future prospects for the 'nickel age' of superconductivity.
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.
