High Temperature Superconducting Oxide Films
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1988The authors used sputter deposition with single oxide targets and metal molecular beam epitaxy to prepare thin films of the high-T/sub c/ oxide Y-Ba-Cu-O superconductor. The processing parameters, the structural characteristics, and the transport properties of the films are reported. The authors also discuss the microstructures of superconducting Y/sub

High-temperature oxidation behaviour of CoCrNi medium-entropy alloy
Corrosion Science, 2020The high-temperature oxidation behaviour of CoCrNi was investigated over different exposure times (6, 12, 24, and 48 h) at 900–1100 °C. The initial phase identification indicated that the tendency of oxide formation at 1100 °C was different after each ...
