Abstract
Highly a-axis oriented HgBa2CaCu2Ox thin films deposited on LaAlO3 sub strates have been exposed to air at room temperature for a period of 4 00 days. The properties of the exposed sample have been studied by ele ctrical and magnetic measurements, X-ray diffractometry (XRD), scannin g 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 O(2)re-ann ealing at 350 degrees C for 16 h.
