Measurement of the magnetic susceptibility of a rod-shaped superconductor using a solenoid coil (SRPM method)

An effective method for the measurement of the magnetic susceptibility ( chi ) of a circular rod-shaped superconductor, in which chi is estimated by substituting the magnetic penetration depth ( lambda ) into a formula after obtaining lambda 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 chi obtained from this method has correlated well with the values measured with a SQUID magnetometer.<
