Electrical and magnetic property measurements at cryogenic temperatures

The properties of materials operating at cryogenic temperatures such as superconductors are investigated. Critical current density at zero and applied magnetic field as a function of angle between the sample and the field is measured. Also, critical transition temperature of superconducting materials are measured using an inductive approach. ac losses of superconductors are measured as a function of field and frequency. Critical current density of superconductors are measured over a temperature range of 4.2 K to 77 K in magnetic fields up to 9 T applied over an angular orientation of 360° with respect to the superconductor axis.
