Abstract

The Josephson plasma resonance is used to study the c-axis supercurrent in the superconducting state of underdoped Bi₂Sr₂CaCu₂O_8+δ with varying degrees of controlled point-like disorder, introduced by high-energy electron irradiation. As disorder is increased, the Josephson Plasma frequency decreases proportionally to the critical temperature. The temperature dependence of the plasma frequency does not depend on the irradiation dose, and is in quantitative agreement with a model for quantum fluctuations of the superconducting phase in the CuO₂ layers.
