Abstract
We have studied aging in laser ablated 2 wt% BaZrO3 doped GdBaCuO (GdBCO) thin films. The films were coated with gold, silver, copper, photoresist and stycast. One film was left without coating for reference. The superconducting and structural properties were followed for several months. The critical temperature Tc and current density Jc were determined from magnetization measurements. The changes in structure were investigated with x-ray diffraction (XRD). It was found that in all the films the superconducting properties deteriorated more than can be accepted during the aging time.
