Abstract :
An effective method for the measurement of the magnetic susceptibility (χ) of a circular rod-shaped superconductor, in which χ is estimated by substituting the magnetic penetration depth (λ) into a formula after obtaining λ from the difference in the impedance between a solenoid coil with a sample and an identical one without a sample, is proposed. The temperature dependence of χ obtained from this method has correlated well with the values measured with a SQUID magnetometer
