- Tl2Ba2CuO6 (Tl-2201) thin films were synthesised on single crystal LaAlO3 and SrTiO3 substrates and on bicrystal LaAlO3 by an ex-situ process. Depending on thallium content and processing conditions, the films were orthorhombic or tetragonal. Tc was in the range 30 – 92 K while Jc reached 4.106A/cm2 at 12 K. By oxygen depletion, Tc was increased by 15 – 20 K for some films.

Journal article (peer-reviewed)abstract
- The vortex dynamics in a Tl2Ba2CuO6 (Tl-2201) thin film with a critical temperature T-c = 80.8 K has been studied by electrical resistivity measurements for magnetic fields 0 less than or equal to B less than or equal to 12 T. The vortex glass line, as determined from the disappearance of linear resistivity, was found to be well described by B-g (T) = B-0[(1 - T/T-c)/(T/T-c)(alpha), with B-0 approximate to 0.65 T and alpha approximate to 1.9. The glass line of Tl-2201 is observed to be located below the one of Tl2Ba2CaCu2O8+delta (Tl-2212) in a magnetic phase diagram based on a reduced temperature scale T/T-c, thus suggesting a higher anisotropy for Tl-2201.
