Investigation of Tc Change Due to Proton Irradiation in TBCCO Superconductors

We studied the effect of 600 keV proton irradiation on thin film cuprate superconductors. A 650 nm thick TBCCO-2212 sample was subjected to a series of proton irradiations totaling a fluence of 5.2 x 10^16 protons/cm^2. Superconducting critical temperature (Tc) was decreased from 100 K towards zero Kelvin, and the normal state resistivity increased accordingly. The rate of Tc reduction to resistivity increase will be used to discuss the fundamental properties of the superconductor.

Abstract

We studied the effect of 600 keV proton irradiation on thin film cuprate superconductors. A 650 nm thick TBCCO-2212 sample was subjected to a series of proton irradiations totaling a fluence of 5.2 x 10^16 protons/cm^2. Superconducting critical temperature (Tc) was decreased from 100 K towards zero Kelvin, and the normal state resistivity increased accordingly. The rate of Tc reduction to resistivity increase will be used to discuss the fundamental properties of the superconductor.
