摘要

The influence of the proton irradiation on the fluctuation-induced conductivity in Ca8.5La1.5(Pt3As8)(Fe2As2)(5) single crystal was investigated. The in-plane magnetoconductivity was measured up to mu H-0 = 13 T. It is observed that the T-c was suppressed up to 30.3 K from 32.5 K as a result of proton irradiation whereas the amplitude of the superconducting fluctuations is almost the same in both pristine and irradiated samples. The magnetoconductivity results analyzed by the Ullah and Dorsey scaling approaches showed that in the pristine sample, the 3D-2D crossover is situated near the T-c. Furthermore, once the 3D-2D crossover occurs, it is found that there is a regime simultaneously described by 2D and 3D fluctuation behaviors in our Ca8.5La1.5(Pt3As8)(Fe2As2)(5) sample. Meanwhile, the proton-irradiated sample showed the 3D fluctuation behavior.
