摘要

Millimeter-sized single crystals of LaFeAsO, LaFeAsO_(1-x)F_x, and LaFe_(1_x)Co,AsO were grown in NaAs flux at ambient pressure. The detailed growth procedure and crystal characterizations are reported. The as-grown crystals have typical dimensions of 3×4×0.05-0.3 mm~3 with the crystallographic c-axis perpendicular to the plane of the platelike single crystals. Various characterizations confirmed the high quality of our LaFeAsO crystals. Co and F were introduced into the lattice leading to superconducting LaFe_(1-x)Co_xAsO and LaFeAsO_(1-x)F_x single crystals, respectively. This growth protocol is expected to be broadly applicable to grow other RMAsO (R=rare earth, M=transition metal) compounds.
