Abstract
YBa2Cu3O7-d thin films were deposited on MgO single crystals by means of an eclipse pulsed laser deposition method. Deposited films are cooled down in situ under an oxygen atmosphere at a given oxygen pressure. The relationsh ip between critical temperature and oxygen deficiency was investigated by m eans of electrical resistance R(T) and x-ray diffraction measurements. Post -deposition cooling is critical and the high pressure of oxygen during cool ing is favorable.
