High Quality YBa2Cu3O7-x Superconducting Thin Films Grown by MOCVD

YBCO thin films have been grown by Metal Organic Chemical Vapour Deposition in ;I cold wall type reactor. The 0-diketonates of yttrium, barium and copper are used as precursors. Filrna have bcen deposited on (001 I MgO and (012) LaA103 single crystalline substrates. The morphology is very dependant on thc gas p h a x composition. Different oxygen partial pressures have been investigated. An inc...

Grain Boundary Induced Magneto-Far Infrared Resonances in Superconducting YBa2Cu3O7−δ Thin Films

Spectral features induced by 45 in-plane misoriented grains have been observed in the far infrared magneto-transmission of YBa2Cu3O7−δ thin films. Two strong dispersive features are found at 80 and 160 cm−1 and a weaker one at 116 cm−1. The data can be well represented by Lorentzian oscillator contributions to the conductivity. Several possible interpretations are discussed. We conclude that th...

Penetration depth measurement in high quality YBa2Cu3O7−x thin films

The parallel plate resonator method has been used for measuring high quality YBa2Cu3O7−x (YBCO) thin films, which have low temperature residual losses comparable to those previously obtained in single crystals. The surface resistance and the real part of the conductivity show a non-monotonic behaviour with a broad peak around 45 K. The penetration depth and the real part of the conductivity var...
