Lattice defect induced nanorod growth in YBCO films deposited on an advanced IBAD-MgO template

“…Recently, a remarkable topic of interest has been dopants that self-assemble themselves during the pulsed laser deposition (PLD) process in a columnar type of manner along the YBCO c-axis, having an effect on the critical current anisotropy by increasing its absolute value along the c-direction. Most commonly used dopants are BaHfO 3 (BHO) [6,7], BaZrO 3 (BZO) [8,9,10] and BaSnO 3 (BSO) [11,12], which form nanorod-type of structures in the PLD process along the YBCO c-axis of varying diameter between 2-12 nm [13,14]. The formation and the properties of the nanorods, such as diameter, are theoretically well understood via behaviour of strain fields in the lattice of the thin film [14,15].…”
