Description

Bi2Sr2-xLaxCu1O6+δ (La-2201) thin films were successfully prepared on (100) SrTiO3 and (100) LaAlO3 substrates by in-situ dc-magnetron sputtering process. A series compensated 2201 targets of La3+ substitution contents for Sr2+ were studied for growing 2201 phase thin films. The superconducting zero resistance temperature Tc,0 reached 19 K. x-ray diffraction analyses showed that films oriented with c-axis perpendicular to the substrate surface and their lattice parameters are around 2.43-2.46 nm. φ-scan and rocking curve show a good epitaxial growth and crystallisation of the films
