Description

Y1-xGdxBa2Cu3O7-d films were deposited by pulsed laser ablation on commercial Hastelloy tapes buffered with IBAD-MgO and LSMO layers. The films were grown with x spanning from 0 to 1 and by varying the deposition conditions.
The films were irradiated using a homogenized XeCl laser beam at varying fluence. The effect of laser irradiation on the structural properties of the films was accurately studied through standard and high-resolution X-ray diffraction and Raman spectroscopy measurements.
The evolution of the cation disorder and micro-strain has been investigated and correlated with the flux pinning properties of the films.
