Complete microwave characterization at 36 GHz of YBaCuO thin films deposited on MgO substrates: influence of the substrate preparation

摘要

This paper deals with the determination of λ and Z{sub}s of YBa{sub}2Cu{sub}3O{sub}(7-δ) thin films deposited on MgO single-crystals, from 36 GHz resonant conical cavity measurements performed in the 25 K to 300 K temperature range. The results are discussed in relation with DC electrical transport properties of the films and also with substrate preparation prior to YBaCuO deposition.
