  • The discovery of superconductivity in the nickelates not only offers a new family of materials to explore but the opportunity to gain further insight into the mechanisms of unconventional superconductivity. Here, the authors employ epitaxial strain to investigate superconductivity in La3Ni2O7 thin films and discuss how changes to the lattice parameters of the parent structure can impact on the observed properties.

  • Unconventional superconductivity is often associated with the presence of other kinds of electronic order. Observations of charge order in infinite-layer nickelate superconductors show that they fit this pattern.

  • Measurements of four different infinite-layer nickelates show that magnetic behaviour coexists with superconductivity. This is different from what is seen in cuprates, giving a strong distinction between the two classes of oxide superconductors.

  • Superconductivity is demonstrated in an infinite-layer nickelate similar to infinite-layer copper oxides, which is synthesized using soft- chemistry topotactic reduction of the perovskite precursor phase.

  • By moving to a substrate that better stabilizes conditions, the doping series of Nd1–xSrxNiO2 is synthesized free from extended defects, resulting in enhancement of superconductivity in terms of transition temperature and range of doping.

  • Nickelate superconductivity has so far been limited to thin films, raising questions about the role of the polar substrate–film interface. Here the authors utilize advanced characterization techniques to reveal the interfacial atomic structure and its relevance for superconductivity.
