Mössbauer Study of Superconductors LaFeO0.88F0.12As

Popis výsledku v původním jazyce

This study continues our investigation of high-temperature superconductors of LaFeO(1MINUS SIGN x)FxAs type initiated in our previous paper (J. Supercond. Nov. Magnetism 27, 1825, [1]), where the high-temperature Kondo effect had been observed in the sample with x = 0.15. We proceed with exploring the properties of the LaFeO0.88F0.12As sample, applying the X-ray diffraction (XRD) method, resistivity measurement, and the magnetic and Mössbauer measurements at the temperature range of 4.2-300 K. We observe the emergence of high-temperature Kondo effect at the temperatures between 30 and 50 K. At the same time, as opposed to the case x=0.15, we reveal the transformation of the high-temperature Kondo effect to the high-temperature superconductivity at thetemperature near 25 K. The Mössbauer spectra of the sample obtained at different temperatures represent a single line, lying near zero relative velocity and do not exhibit any visible alterations. Concurrently, the application of an exter
