Abstract :High T_e superconducting YBaCuO thin film have been prepared on MgO (100) substrate by RF magnetron sputtering using single target under sputtering gas pressures ranging from 5 mTorr to 1Torr. Critical temperature T_<con> of the films on the substrates positioned right above target center decreased with increasing sputtering gas pressure, while that of the films on substrates positioned right above erosion area decreased at pressure below 50mTorr. The composition ratios Ba/Y and Cu/Y of films were increased with increasing sputtering gas pressure. This tendency was remarkable at position right above erosion area.
