Two-electronic component behavior in the multiband FeSe${}_{0.42}$Te${}_{0.58}$ superconductor

D. Arcon, P. Jeglic, A. Zorko +5

We report X-band EPR and ${}^{125}$Te and ${}^{77}$Se NMR measurements on single-crystalline superconducting FeSe${}_{0.42}$Te${}_{0.58}$ ($T_c$ = 11.5(1) K). The data provide evidence for…
