Abstract

Recently increasing the J_c 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 J_c 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 J_c 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.
