Thallium barium calcium copper oxide, or TBCCO (pronounced "tibco"), is a family of high-temperature superconductors having the generalized chemical formula TlmBa2Can−1CunO2n+m+2. Tl2Ba2Ca2Cu3O10 (TBCCO-2223) was discovered in Allen M. Hermann's laboratory in the physics department of the University of Arkansas in October 1987 by the post-doctoral researcher Zhengzhi Sheng. The bulk superconductivity in this material was confirmed by observations of magnetic flux expulsion and flux trapping signals (under zero field cooled and field cooled conditions) with a SQUID magnetometer in the superconductor laboratory of Timir Datta in the University of South Carolina. Allen Hermann announced his discovery and the critical temperature (Tc) of 127 K, in Houston, Texas at the World Congress on Superc

  • Tlenki talowo-barowo-wapniowo-miedziowe (TBCCO - skrót od ang. thallium barium calcium copper oxide, wym. "tibko") - grupa nadprzewodników wysokotemperaturowych o wzorze ogólnym TlmBa2Can−1CunO2n+m+2+δ, gdzie δ oznacza niedobór atomów tlenu niezbędny do nadprzewodzenia. Tlenki TBCCO podobnie jak inne nadprzewodniki miedziowe (YBCO, BSCCO) oznacza się symbolami składającymi się z cyfr oznaczających współczynniki stechiometryczne. Niektóre spośród tlenków TBCCO wykazujących nadprzewodnictwo wraz z ich oznaczeniami zestawiono w tabeli:
