Here we present signatures of superconductivity in La_3Ni_2O_7 thin films at ambient pressure, facilitated by the application of epitaxial compressive strain. The onset T_c varies roughly from 26 to 42 K, with higher T_c values correlating with smaller in-plane lattice constants. We observed...
Studying the electronic ground state of La3Ni2O7-δfilms with varying oxygen concentrations could have important implications for understanding the superconductivity discovered under pressurized conditions. In unconventional superconductors, various orderings, such as spin order, charge order, and spin-charg...
