Mapping out the spin fluctuations in Co-doped LaFeAsO single crystals by NMR

Piotr Lepucki, Raphael Havemann, Adam P. Dioguardi +7

We determine the phase diagram of LaFe${}_{1-x}$Co${}_x$AsO single crystals by using nuclear magnetic resonance (NMR). Up to a nominal doping of $x=0.03$, it follows the phase diagram…
