Abstract

Thin films of Tl 1Ba 2Ca 2Cu 3O 9+x have been grown on single crystal (110) LaAlO 3 by a metal-organic chemical vapor deposition process employing Ba(hfa) 2.mep, Ca(hfa) 2.tet, and Cu(dpm) 2 (hfa = hexafluoroacetylacetonate; dpm = dipivaloylmethanate; tet = tetraglyme; mep = methylethylpentaglyme) as the volatile metal sources. A subsequent phase-selective annealing procedure accomplishes thallination using TlF in a bulk oxide pellet. The resulting films are nearly phase-pure and highly oriented and contain negligible fluoride by windowless energy-dispersive x-ray measurements. The films exhibit transport measured T c = 103 K and J c > 10 4 A/cm 2 (77 K, 0 T) and at low temperatures retain J c > 10 5 A/cm 2 (5 K, 4.5 T) as measured by magnetic hysteresis.
