520 _ _ |a Scanning tunnelling spectroscopy measurements were performed on thin films of La0.7Sr0.3MnO3 both at room temperature and liquid nitrogen temperature. While no inhomogeneities were recorded at liquid nitrogen temperature on any sample, clear evidence of spectroscopic inhomogeneities was evident in tunnelling conductance maps collected at room temperature. The investigated films exhibit a transition from a ferromagnetic-metallic to a paramagnetic-insulating state at around room temperature, so the observed spectroscopic features can be interpreted within a phase separation scenario. A quantitative analysis of the observed spectroscopic features is reported, pointing out the occurrence of phase modulation and its possible correlation with the properties of the system.
