The degradation of the surface resistance Rs of YBCO material by ion milling is usually supposed to be linked to oxygen loss and crystallographic defects. To study this effect, the structural and physical analysis of the milled YBCO thin film has bee

Mechanism of oxygenation of YBaCuO thin films during in-situ growth in presence of oxygene plasma: correlation between oxygenation and physical properties

Autor: J. Garcia-Lopez, Julius Siejka, Yves Lemaitre

Publikováno v: Superconducting and Related Oxides: Physics and Nanoengineering III.

The emphasis is on the study of the relationship between oxygen profiles, crystallographic structure and electrical and physical properties of the YBaCuO thin films formed in situ at the same and optimized conditions of sample deposition for the micr
