A study of the effect of the oxygen index of the target on the critical characteristics of YBa$_2$Cu$_3$O$_x$ epitaxial layers formed by pulsed laser deposition
Abstract:
The effect of radiative heating of the surface of an HTS target on its oxygen index during the growth of HTS coatings by pulsed laser deposition is studied. It is shown that, during growth, the oxygen index of the HTS target varies in a range of 6.85–6.12. It is revealed that the oxygen index of HTS coatings formed by pulsed laser deposition does not depend on the oxygen index of the sputtering target at an identical cationic composition.
