| dc.description | We prepared superconducting films at lower temperatures by a pulsed laser deposition method. The growth temperature usually decreased with decreasing oxygen pressure in the deposition chamber. However, the superconducting critical temperature of the films deposited at a low oxygen pressure was drastically degraded because of insufficient oxidation. In this work, we employed a mixed gas consisting of oxygen and ozone as the oxidation gas. As a result, increased to 86 K, when films were deposited in a low-pressure oxygen atmosphere (5 mTorr) mixed with ozone (5 mol%) and at a low laser fluence of . In addition to superconducting properties, the surface morphology could be improved by using low-pressure oxygen gas mixed with ozone and by optimizing the laser fluence. |
