1 Answer. The compound YBa 2Cu 3O 7, which shows superconductivity , has copper in oxidation state +7/3 Assume that the rare earth element yttrium is in its usual +3 oxidation state.
What are the two physical properties that characterize YBa2Cu3O7 as a superconductor?
The two key properties of superconductors – the expulsion of magnetic fields and perfect conductivity – were explained phenomenologically through the London theory developed by Fritz and Heinz London in 1935 [4].
What is the critical temperature of YBa2Cu3O7?
Among REBCO high-temperature superconductors, YBa2Cu3O7−x (YBCO) is the most extensively studied because of its high critical temperature of 92 K and because, when prepared in the form of thin film or coated conductor, it can carry high electric currents at high magnetic fields [10], [11], [12].
Which is the 123 superconductor?
Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that displays high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen (77 K) at about 92 K….Yttrium barium copper oxide.
