	abstract = {XRD, magnetic and EPR studies of the mixed phase La0.5Gd0.5Ba2Cu3Oy high-Tc superconductor after prolonged (one year) {\textquoteleft}aging{\textquoteright} at room temperature are reported. Within this time period a pronounced change of the superconducting behavior and the homogeneity of the diamagnetic shielding signal accompanied by substantial structural changes, reduction of the impurity phase BaCuO2+x and increase of the EPR spectrum{\textquoteright}s intensity of Cu2+ magnetic defects is detected. The {\textquoteleft}aging{\textquoteright} effects are related to strain-relaxation taking place during room temperature annealing that induces the formation of Cu2+ defect centers.},
