Superconductivity and antiferromagnetic ordering in the high-field paramagnetic oxypnictide NdFeAsO0.94F0.06

We present measurements of the temperature and field dependencies of the magnetization $M(T,H)$ of ${\text{NdFeAsO}}_{0.94}{\text{F}}_{0.06}$ at fields up to 33 T to probe the coexistence of superconductivity with global antiferromagnetic ordering. Although $M(T,H)$ at $48
