High-temperature superconducting thick films

Abstract

High-temperature superconducting (HTS) thick films have undergone a period of rapid progress since their discovery in 1986. In this review thick-film materials are described with special reference to their processing, their properties and the development of devices. The devices include HTS magnetic shields, resonators for microwave filters, antennas and wire. The translation of science into applications has taken place in a relatively short time and already impressive performance is seen in HTS prototype devices.

Effect of Magnetic Field Direction on Magnetoresistivity, Activation Energy, Irreversibility and Upper Critical Field of Bi-2212 Thin Film Fabricated by DC Sputtering Method

“…The Bi-Sr-Ca-Cu-O (BSSCO) materials, one of the cuprate high-temperature superconductor families, have widely been investigated because of their higher critical temperature, remarkable smaller power losses, higher current and magnetic field carrying capacity, optical and electronic properties [5][6][7][8][9][10][11][12][13]. Moreover, in the literature there have been several reports relating to BSCCO films for high frequency applications including filters, antennas and magnetic shield devices [14][15][16][17]. This family has three different phases with regard to chemical compositions: the Bi-2201 phase with T c of ≈ 20 K, Bi-2212 phase with T c of ≈ 85 K and Bi-2223 phase with T c of ≈ 110 K [18].…”

“…In order to overcome these problems appeared, the flux pinning mechanism in the film should be investigated in detail. In the recent works [12][13][14][15][16][17][18][19][20][21][22][23][24], the researchers have extensively analyzed the flux pinning mechanism in the superconducting state to introduce the effective pinning centers such as planar defects, stacking faults, and microdefects, resulting in thermally activated jumps; or hopping of flux lines; or flux bundles over an energy barrier [25,26]. Over the pinning energy barrier of a structure, the flux line might be thermally activated although the Lorentz force exerted on the flux bundle by the current is smaller than the pinning force [27][28][29][30].…”

YBa2Cu3O7 melt textured thick films grown by infiltration process on YSZ substrate prepared by sol–gel method

“…for high power microwave resonators, superconducting fault limiters, magnetic shields, filters and antennas [1][2][3][4]. The thick film technologies allow the low cost production of large area coatings of complex shape with relative ease.…”

“…In consequence of the reactions between film and substrate, the superconducting phase is frequently deteriorated. Among the ceramic materials yttria-stabilized zirconia (YSZ) is mostly suited as substrate for preparation of melt textured YBCO thick films [1,[13][14][15]. YSZ substrates with high density and closed porosity are necessary.…”

Single Sensor High-Temperature Superconducting Axial Gradiometer With Thick Film Pick-Up Loops

“…It was fabricated from a melt-processed (YBCO) thick film of thickness 50 deposited on a mechanically stable, electrically inert substrate of yttria-stabilized zirconia (YSZ), which we commercially obtained [7] with the patterning of the pick-up loops performed by a proprietary technique. The detailed process used to fabricate the thick film has been reported elsewhere [8].…”
