Abstract

The presence of macroscopic phase separation into superconducting and spin-glass-like magnetic phases in LaFeAs(O_1-xF_x) is demonstrated by muon spin rotation measurement in a sample near the phase boundary (x = 0:06). Both magnetism and superconductivity develop simultaneously below a common critical temperature, T_m ≃ T_c ≃ 18 K. This remarkable accordance strongly suggests that the electronic correlations leading to these two competing ground states share a common origin.
