Microwave Absorption Study on YBa2Cu3Oy/MgO at Low Magnetic Fields
Non-resonant microwave absorption (NRMA) studies have been done for YBa2Cu3Oy film (≃800Å) fabricated on MgO (100) substrate. NRMA signals, either from film surface or interface, were separately observed below Tc...

Observation of Early Stages of YBCO Films Grown on MgO(100) Step Substrates
We have investigated the early stages of YBa2Cu3O7-x (YBCO) films grown by sputtering onto step substrates with different terrace width and step height. It was found that the transition film thickness from two di...

Effects of Water and Organic Solvents on the Bi-Pb-Sr-Ca-Cu-O System
We report the change in the superconductivity characteristics as a sample of the Bi-Pb-Sr-Ca-Cu-O system is soaked in the distilled water or in a certain organic solvent. The critical temperature shows a tende...
