英文摘要	We report single-crystal growth of a La0.34Na0.66Fe2As2 iron-based superconductor several millimeters in size. The samples were accidentally obtained in trying to grow LaFeAsO1-yFy (y >= 0.8) single crystals with NaAs and NaF flux. The sample shows both antiferromagnetic and structural transitions at 106 K. The superconducting transition temperature is about 27 K with a superconducting anisotropy of about 1.9. These values and the temperature dependence of the Hall coefficient suggest that La0.34Na0.66Fe2As2 belongs to the hole-doped '122' families of iron pnictides with the doping level slightly lower than optimal doping. Compared with previous reports on the polycrystalline samples, our results suggest that either the T-c of the this system can be further increased, or the superconducting dome may not be well formed in this system. In either case, the La0.5-x,Na0.5+x,Fe-2 As-2 system provides a new platform to study the antiferromagnetic and superconducting properties of iron-based superconductors.
