Abstract

Oxypnictide superconductors: Behaviour in very high magnetic fields The synthesis of the novel superconductor LaFeAsO0.89F0.11 with transition temperature Tc ∼ 26 K has been quickly followed by reports of even higher Tcs. These discoveries have generated much interest in the mechanisms and manifestations of unconventional superconductivity in the family of doped quaternary layered oxypnictides, because many features of these materials set them apart from other superconductors. Hunte et al. report very high-field resistance measurements of LaFeAsO0.89F0.11 up to 45 T, which show a remarkable enhancement of the upper critical field Bc2 as compared to values expected from the slopes dBc2/dT ≈ 2 T/K near Tc, particularly at low temperatures where the deduced Bc2(0) ≈ 63–65 T exceeds the paramagnetic limit.
