摘要：

BaFe2(As0.67P0.33)(2) (Ba122:P) thin films were fabricated on (LaAlO3)(0.3)-(SrAl0.5Ta0.5O3)(0.7) (LSAT) (100) substrates by a pulsed laser deposition method using a second-harmonic Nd:YAG laser. Superconducting Ba122:P thin films with c-axis orientation and in-plane alignment were successfully obtained. Detailed structural properties on the films were investigated by X-ray diffraction. The X-ray pattern suggested the existence of some apatite-type phase. Transmission electron microscope observation revealed the formation of a reacted layer between the film and the substrate. The reacted layer had a Ba(Sr)-rich and P-rich composition. These analyses indicated the formation of an apatite material at the interface of the film and the substrate. (C) 2014 Elsevier B.V.
