Hall effect and magnetoresistance in the normal state of the superconductor LaO${}_{0.9}$F${}_{0.1-x}$FeAs

Huan Yang, Xiyu Zhu, Lei Fang +2

By using a two-step method, we successfully synthesized the iron based new superconductor LaO${}_{0.9}$F${}_{0.1-x}$FeAs. The Hall effect and magnetoresistance were measured in wide te…
