High-field electron spin resonance spectroscopy study of GdO${}_{1-x}$F${}_x$FeAs superconductors

A. Alfonsov, F. Murányi, V. Kataev +16

We report a detailed investigation of GdO${}_{1-x}$F${}_x$FeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with mea…
