According to a study from Liege, Belgium, "We have studied numerically and experimentally the magnetic flux penetration in high-T-c superconducting tube subjected to a uniform magnetic field parallel to its long axis. This study is carried in view of designing low-frequency magnetic shields by exploiting the diamagnetic properties of high-T-c superconducting ceramics."
"We have measured the field attenuation for applied magnetic fields in the frequency range 5 mHz - 0.1 Hz by Hall probe measurements and at audio frequencies using a sensing coil. A simple 1D analysis using the Kim critical state model was found to be able to reproduce the experimental data ...
