| 内容記述 | A Mössbauer spectroscopy study of the iron-based superconductor KxFe2−ySe2, with two superconducting phases of SC1 and a pressure induced SC2 was performed under pressure. This compound consists of two separated phases of major magnetic (non-superconducting) and minor superconducting components. The internal magnetic field of the major magnetic component decreased at the SC2 phase and disappeared around 15 GPa, while that of the minor non-magnetic component maintained its intensity up to 14.9 GPa. Multiple internal magnetic fields were introduced for improved fits to the spectra of the magnetic component at the SC2 phase, suggesting the importance of the electron–electron correlation in the emergence of the SC2 phase. | |||||
