Superconducting thin films of Tl"2Ca"2Ba"2Cu"3O"y and Tl"2CaBa"2Cu"2O"y
We present techniques for preparing unoriented polycrystalline and epitaxial superconducting thin films of the Tl"2CaBa"2Cu"2O"y and Tl"2Ca"2Ba"2Cu"3O"y phases on a wide variety of substrates. The crucial steps determining the properties of the films are...

| 520 | |a We present techniques for preparing unoriented polycrystalline and epitaxial superconducting thin films of the Tl"2CaBa"2Cu"2O"y and Tl"2Ca"2Ba"2Cu"3O"y phases on a wide variety of substrates. The crucial steps determining the properties of the films are shown to be the air sintering and oxygen annealing following the initial metal deposition by electron beam evaporation under a slight oxygen overpressure. A sintered Tl-Ca-Ba-Cu-O pellet is employed as a source of excess Tl during sintering and annealing of the thin film. The Tl concentration in the final films controls the nature of the intergrain connections. The films are characterized by their structural, chemical, magnetic and transport properties. Zero resistance typically occurs at 97 K for Tl"2CaBa"2Cu"2O and at 106 K for Tl"2Ca"2Ba"2Cu"3O"y. Transport critical currents of up to 110 000 A/cm^2 have been obtained at 77 K for unoriented Tl"2CaBa"2Cu"2O"y, up to 160 000 A/cm^2 for epitaxial Tl"2Ca"2Ba"2Cu"3O"y and up to 240 000 A/cm^2 for unoriented Tl"2Ca"2Cu"3O"y films with little field dependence of the critical current observed. | ||

Superconducting thin films of Tl"2Ca"2Ba"2Cu"3O"y and Tl"2CaBa"2Cu"2O"y |
| abstract |
We present techniques for preparing unoriented polycrystalline and epitaxial superconducting thin films of the Tl"2CaBa"2Cu"2O"y and Tl"2Ca"2Ba"2Cu"3O"y phases on a wide variety of substrates. The crucial steps determining the properties of the films are shown to be the air sintering and oxygen annealing following the initial metal deposition by electron beam evaporation under a slight oxygen overpressure. A sintered Tl-Ca-Ba-Cu-O pellet is employed as a source of excess Tl during sintering and annealing of the thin film. The Tl concentration in the final films controls the nature of the intergrain connections. The films are characterized by their structural, chemical, magnetic and transport properties. Zero resistance typically occurs at 97 K for Tl"2CaBa"2Cu"2O and at 106 K for Tl"2Ca"2Ba"2Cu"3O"y. Transport critical currents of up to 110 000 A/cm^2 have been obtained at 77 K for unoriented Tl"2CaBa"2Cu"2O"y, up to 160 000 A/cm^2 for epitaxial Tl"2Ca"2Ba"2Cu"3O"y and up to 240 000 A/cm^2 for unoriented Tl"2Ca"2Cu"3O"y films with little field dependence of the critical current observed. |
