Preparation and properties of high-Tc superconducting Tl-1223 thick films obtained by screen-printing method

Polycrystalline (Tl0.5Pb0.5)(Sr0.9Ba0.1)2Ca2Cu3Oy superconducting thick films with high critical current densities

“…We have been active in the fabrication of highly textured polycrystalline Tl-1223 films via screen printing [13][14][15]. This method does not require complicated preparation procedures such as vacuum techniques and allows the printing of various patterns.…”

Temperature and Magnetic Field Dependences of Critical Current of Thallium-Based Superconducting Films

“…Samples 1 and 2 were prepared by screen printing thallium-free precursor material on monocrystalline (100) lanthanum aluminate substrates followed by ex situ thallination. The preparing procedures are described in earlier papers [1,2,5,6]. The resulting films were quasi-monocrystalline with high ab alignment and c-axis orientation and of high purity.…”

Microstructure dependent microwave properties of spray deposited Tl–Ba–Ca–Cu–O films

“…The phases with one Tl-O layer, especially TlBa 2 Ca 2 Cu 3 O z (Tl-1223, T c = 115 K), are good candidates for coated conductor power applications because of their stronger interlayer coupling between Cu-O planes, where as phases with two Tl-O layers (Tl 2 Ba 2 CaCu 2 O z , Tl-2212, T c = 110 K and Tl 2 Ba 2 Ca 2 Cu 3 O z , Tl-2223, T c = 125 K) are promising for passive microwave devices [1]. The chemical solution routes of the deposition-like Screen printing [2] electrochemical route [3][4][5] and spray pyrolysis [6][7][8] are preferred for preparing large-scale coatings in industry because of easier production and their low capital costs. However, very little attention has been paid to the microwave properties of these films.…”
