Resistivity saturation in PrFeAsO${}_{1-x}$F${}_y$ superconductor: An evidence of strong electron-phonon coupling

D. Bhoi, P. Mandal, P. Choudhury

We have measured the resistivity of PrFeAsO${}_{1-x}$F${}_y$ samples over a wide range of temperature in order to elucidate the role of electron-phonon interaction on normal- and super…
