We develop a way to stabilize in air the transferrable templates for ex situ epitaxial growth of oxide nanomembranes using other techniques. In this manner, freestanding superconducting SrTiO3 membranes were synthesized ex situ using molecular beam epitaxy. This study paves the way for the synthesis of an expanded selection of freestanding oxide membranes and heterostructures.

We perform highly localized spectroscopic measurements (EELS) to reveal a number of key differences between the superconducting cuprates and nickelates, particularly with regard to the hybridization between the O and metal (Cu or Ni) orbitals.

We find that the upper critical field of the infinite-layer nickelate superconductor Nd0.775Sr0.225NiO2 is surprisingly isotropic at low temperatures despite the layered crystal structure. In a magnetic field, the superconductivity is strongly Pauli-limited, such that the paramagnetic effect dominates over orbital de-pairing.

The phase diagram of an additional family of nickelate superconductors has been discovered, which marks the first step towards establishing a more generic superconducting phase diagram of the nickelates enriched with many exotic properties and intriguing physics.
