N2 - Recently increasing the Jc at higher magnetic field can be accomplished by introducing artificial pinning center (APC) into REBCO coated conductor and films. In particular, in impurity additions, nano-BaZrO 3 (BZO) rods in PLD-YBCO and GdBCO coated conductor have been investigated for c-axis correlated flux pinning. We have reported the high Jc SmBCO and (Nd,Eu,Gd)BCO films and coated conductor using usual PLD, low temperature growth (LTG) and Vapor-liquid-solid growth (VLS) technique. In this research we studied the controlling the nanorods BZO growth mechanism by initial deposition of nanodots on the surface for improving the Jc at magnetic field. REBCO+BZO film are found to have superior performance in magnetic field at all field orientations, suggesting the presence of BZO-rods with optimized shape and density caused increasing BZO-dots at nuclear growth. The present work has confirmed that the control of APC initial growth is a promising technique to produce flux pinning center.
