Abstract Highly a-axis oriented HgBa2CaCu2Ox thin films deposited on LaAlO3 substrates have been exposed to air at room temperature for a period of 400 days. The properties of the exposed sample have been studied by electrical and magnetic measurements, X- ray diffractometry (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectrometry (EDX). No substancial change of superconducting transition temperature or the structure was observed, but c-peaks reappeared after O2 re-annealing at 350°C for 16 h.
