D. Ariosa et al., SUPERCONDUCTIVITY AND QUANTUM FLUCTUATIONS IN HIGH T(C) ALLOYS AND MULTILAYERS, Physica. B, Condensed matter, 194, 1994, pp. 2371-2372
The superconducting transition temperatures T(c) of (Y1-xPrx)Ba2Cu3O7
alloys and YBa2Cu3O7/PrBa2Cu3O7 multilayers are explained by a common
dominant mechanism: The 2D quantum fluctuations of the superconducting
order parameter phase.
