The discovery of an infinite layer nickelate superconductor in 2019 marked a new era of nickel-based superconductivity and provided opportunities to understand the origin of high-T-c superconductivity. Tremendous efforts are now being made in both experimental and theoretical aspects to explore this new superconducting family.
The discovery of an infinite layer nickelate superconductor in 2019 provided a perfect ending to the long race of searching nearly 30 years for a cuprate analog and at the same time marks a new era of nickel-based superconductivity. The similarities and differences between nickelates and cuprates provide great opportunities for us to reveal the origin of high-T-c superconductivity. Therefore, the observation of nickelate superconductivity is now motivating tremendous efforts to look into this new superconducting family from both aspects of experiment and theory. Here, we give an early perspective on the superconductivity in nickelates, including (1) the theoretical explorations and main conclusions in the past; (2) the newly discovered superconductor R1-xSrxNiO2, in terms of its synthesis, electronic structure, and comparison with cuprates; and (3) the future perspectives of nickelate superconductivity.
