High superconducting anisotropy and weak vortex pinning in Co doped LaFeAsO

G. Li, G. Grissonnanche, J. -Q. Yan +4

Here, we present an electrical transport study in single crystals of LaFe${}_{0.92}$Co${}_{0.08}$AsO ($T_c\simeq 9.1$ K) under high magnetic fields. In contrast to most of the previou…
