Anomalous behaviour of the in-plane electrical conductivity of the layered superconductor $\kappa$-(BEDT-TTF)$_2$Cu(NCS)$_2$

, 2003
The quasiparticle scattering rates in high-quality crystals of the quasi-two-dimensional superconductor $\kappa$-(BEDT-TTF)$_2$Cu(NCS)$_2$ ~are studied using the Shubnikov-de Haas effect and MHz penetration-depth experiments.

Analysis of Using Acoustic Microscopy to Evaluate Defects in Spot Welding Joints

Archives of Metallurgy and Materials, 2016
The article presents the possibilities of using acoustic microscopy to evaluate defects in resistance spot welding joints. For this purpose, the welded joints were made from two grades of aluminium plates EN AW5754 H24 and EN AW6005 T606, which were then
