A unified phase diagram of F-doped LaFeAsO by means of NMR and NQR parameters

Hans-Joachim Grafe, Piotr Lepucki, Markus Witschel +5

We present ${}^{75}$As Nuclear Magnetic and Quadrupole Resonance results (NMR, NQR) on a new set of LaFeAsO${}_{1-x}$F${}_x$ polycrystalline samples. Improved synthesis conditions led to…
