Analysis of fluctuation conductivity of polycrystalline Er1-xPrxBa2Cu3O7-δ superconductors
High-TC Superconductor Erbium Praseodymium Critical Phenomena
2010/7/8
In this work we report on conductivity fluctuation measurements in polycrystalline samples of the Er1−xPrxBa2Cu3O7−d superconductor (x =0.00, 0.05 and 0.10). Samples were prepared by a sta...
