Tunable superconductivity and spin density wave in La3Ni2O7/LaAlO3 thin films
Yu-Han Cao, Kai-Yue Jiang, Hong-Yan Lu +2
Recently, La3Ni2O7 thin film on the LaAlO3 substrate is shown to be superconducting, while the bulk La3Ni2O7 with the same in-plane lattice constant under pressure does not superco…
