Measuring resistance of a high temperature superconducting sample 

This application note describes an experiment to measure the resistance of High Temperature Superconductor (HTS) tape and determine the superconducting transition temperature, Tc. The measurements were carried out using Oxford Instruments’ OptistatDry cryogenic system with the demountable sample puck option, combined with a Zurich Instruments’ MFLI (Medium Frequency Lock-In) amplifier. The experiment demonstrates the adaptability and controllability of the cryogenic platform as well as the ability of the MFLI to resolve small signals with excellent background noise rejection. Download the application note below to know more.
