A Method for Simultaneously Measuring Resistivity and the Meissner Effect of a Superconductor Used with a Solenoid Coil

Abstract

From the differences in reactance and resistance between a circular solenoid coil surrounding and coaxial with a cylindrical conductor and a similar coil without the conductor, a method for measuring resistivity and permeability of the conductor is proposed. The resistivity of copper measured by this method has correlated well with the values measured by the DC four-probe method. Furthermore, the experiment with a high Tc superconductor indicates that the resistivity and permeability of the conductor can be measured with remarkable accuracy.
