Title
Flux Pinning Properties and Microstructure in 
Films With  nanorods into REBa<sub>2</sub>Cu<sub>3</sub>O<sub>y</sub>(REBCO) films is actively discussed. However, the growth mechanisms of the BZO nanorods are still evidently unexplained. In this study, in order to control the growth of BZO nanorods in REBCO films, we fabricated the Sm<sub>1+x</sub>Ba<sub>2-x</sub>Cu<sub>3</sub>O<sub>y</sub> (SmBCO) films containing BZO by conventional pulsed laser deposition (PLD-Sm+BZO) and vapor-liquid-solid technique (VLS-Sm+BZO). The self field <i>Jc</i>´s of PLD- and VLS-Sm+BZO films showed 1.3 MA/cm<sup>2</sup> and 1.2 MA/cm<sup>2</sup>, respectively. However, magnetic field dependence of the <i>Jc</i> for the VLS-Sm+BZO film was twice as high as that of the PLD-Sm+BZO film at 77 K, B = 5 T. From a microstructure analysis, we found the BZO nanorods in VLS-Sm+BZO film grew nearly straight along the c-axis of the SmBCO.</div></div>
