Abnormal enhancement of ferromagnetism for LaMnO3+δ thin films with decreasing oxygen pressure
The compressive LaMnO3+δ thin films with thickness of ∼20 nm are grown on LaAlO3 (001) single crystal substrates under various oxygen environment. With decreasing oxygen pressure, the in-plane compressive strain is enhanced. It is found that the breathing mode (Q1) and the basal plane distortion mod...
