Abstract

This study investigated the application of pressure on the superconducting properties of a thallium-based cuprate, namely Tl₂Ba₂Ca₂Cu₃O_9-δ (Tl-2223). The superconducting transition temperature (T_c) and the critical current density (J_c) were studied by applying ~1 GPa of pressure. This hydrostatic pressure was applied in a piston-cylinder-cell (PCC), using Pb as a manometer and Daphne 7373 oil as the pressure transmitting medium. For estimating the J_c, we used Bean’s critical state formula on the magnetic hysteresis curves at 10 K and 20 K. Both the T_c and J_c improved with pressure. The J_c values increased at both temperatures and the Tc value increased by 4 K with a pressure of 0.8 GPa. These results clearly indicate that pressure is another tool to control properties of quantum materials.

Using a cryogenic diamond anvil cell (DAC) the pressure dependence of the superconducting transition temperature {ital T}{sub {ital c}} of Tl{sub 2}Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10+{ital y}} (Tl-2223) and Tl{sub 2}Ba{sub 2}Ca{sub 3}Cu{sub 4}O{sub 12+{ital y}} (Tl-2234) has been measured resistively up to 21 GPa. At ambient pressure these compounds have {ital T}{sub {ital c}}{close_quote}s of 128.5 K and 113 K. At low pressures, the pressure dependence {partial_derivative}{ital T}{sub {ital c}}/{partial_derivative}{ital p} is 1.75 K/GPa in Tl-2223 and 2.0 K/GPa in Tl-2234.

The synthesis of superconducting Tl--Ca--Ba--Cu--oxide films by the reaction of spray deposited Ca--Ba--Cu--oxide precursors with Tl sub 2 O vapor in a two-zone reactor

Journal Article DeLuca, J A ; Garbauskas, M F ; Bolon, R B ; ... - Journal of Materials Research; (USA)

Superconducting Tl--Ca--Ba--Cu--oxide films have been prepared on yttria stabilized zirconia substrates via the reaction of Tl{sub 2}O vapor with precursor Ca--Ba--Cu--oxide films prepared by the spray pyrolysis of a solution of the metal nitrates. The vapor reaction process, evaluated in both air and oxygen ambients, was carried out in a two-zone reactor which permitted the independent control of the temperatures of the sample and of a boat containing thallium oxide. Sample temperatures of 865--905 {degree}C and boat temperatures of 775--870 {degree}C were investigated.

Journal Article Tatsuki, T ; Tokiwa-Yamamoto, A ; Tamura, T - Journal of Low Temperature Physics

The authors have recently synthesized new superconducting cuprates containing a mercury-based bilayer, i.e. (Hg, Tl){sub 2}Ba{sub 2}(Ca,Y)Cu{sub 2}O{sub y} and (Hg{sub 1{minus}x}Tl{sub x}){sub 2}Ba{sub 2}Ca{sub n{minus}1}Cu{sub n}O{sub y} (x {approximately} 0.4, n = 3,4) by a high-pressure technique. These compounds are the n= 2, 3, and 4 members of a new homologous series, (Hg,Tl)-22(n {minus} 1)n. The effects of Tl substitution for Hg on the formation and superconductivity of the (Hg,Tl)-2223 and -2234 phases are investigated. Both the phases are stabilized for the Tl content x of 0.3-0.6.

Critical current density of (Tl{sub 1-x}Hg{sub x})Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub 8+{sigma}} superconductor

Journal Article Chang, I C ; Liu, J Z ; Klavins, P ; ... - Journal of Superconductivity

Polycrystalline samples with superconducting transition temperatures higher than 130 K have been synthesized in the system Tl{sub 1{minus}x}Hg{sub x}Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub 8+{delta}} with x = 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9. The magnetization data of these samples as a function of applied magnetic field up to 5.5 T are measured in a SQUID magnetometer over a wide temperature range. These hysteresis curves are analyzed with the Bean critical-state model to estimate the intragrain critical current density, J{sub c}. The results show that the values of J{sub c} are comparable to the values of YBCO and the early reportedmore »« less

Journal Article Malandrino, G ; Richeson, D S ; Marks, T J ; ... - Applied Physics Letters; (USA)

Films of the Tl{sub 2}Ba{sub 2}Ca{sub {ital n}{minus}1}Cu{sub {ital n}}O{sub 2{ital n}+4} high {ital T}{sub {ital c}} superconductors ({ital n}=2 or 3) can be prepared with a high degree of phase selectivity using a combination of metalorganic chemical vapor deposition (MOCVD) and vapor diffusion. Ba-Ca-Cu-O films are first prepared by MOCVD using the volatile metalorganic precursors Ba(hexafluoroacetyl- acetonate){sub 2}(tetraglyme), Ca(dipivaloylmethanate){sub 2}, and Cu(acetylacetonate){sub 2}. The second-generation'' barium precursor exhibits significantly improved thermal stability and volatility over previously used compounds. Thallium is then incorporated into these films by vapor diffusion using a Tl-Ba-Ca-Cu oxide mixture of controlled composition as the sourcemore »« less
