High temperature superconductors HTSC

Figure 1.18, An HRTEM image of coherent intergrowths in TlBa2Ca4Cu50i3 (1245), a high-temperature superconductor (HTSC) with five Cu-O layers. Four Cu-O layers (arrowed) of the 1234 HTSC phase are intergrown in the five Cu-O layer compound. (After Gai 1992.)...

Soon after the discovery of high-temperature superconductors (HTSC) and, in particular, the YBCO compound there were grand predictions that these materials would revolutionize areas such as a high-speed transporta-... 

A good example of the power of synchrotron source radiation is found in the study of the thin-film superconductors that are required for applications of high-temperature superconductors (HTSC) in microelectronics technology [77]. An example of such work [78] involves the analysis of HTSC films produced by laser evaporation of elements in the Y-Ba-Cu-0 system. Ten films were simultaneously deposited with various target-to-substrate distances allowing study to be made of the laser plasma expansion in vacuo. A very important advantage of this method is that it allows extremely low detection limits to be achieved. As an example, in the referenced study [78] the authors claim a detection limit of 5 x lO atoms/cm. ... 

The first superconducting compound with Tc above the boiling point of liquid nitrogen (T 77 K) was discovered as a mixed copper oxide representative of the system Y—Ba—Cu—O at ambient pressure by Wu et al. in 1987 [2.25], and marked the beginning of the worldwide high-temperature superconductor (HTSC) research. Since then, YBa2Cu307 3 is one of the compounds studied most frequently. It is often abbreviated as Y-123 or YBCO . 

At the peak of the high-temperature superconductor (HTSC) ceramic hype during the late 1980s (see Chapter 9), the quest for YBCO (yttrium barium copper...
