Diversity of electronic states of Nd0.5Sr0.5MnO3Nd0.5Sr0.5MnO3 revealed by soft X-ray photoemission

The electronic states of the Nd0.5Sr0.5MnO3Nd0.5Sr0.5MnO3, which shows various electronic phases such as paramagnetic insulator, ferromagnetic metal, and the charge-ordered insulator depending on the temperature, have been revealed by high-resolution Mn 2p–3d resonant photoemission and X-ray absorption spectroscopy. These results indicate the importance of the relationship between electronic states and the Jahn–Teller effect.
