A method to measure the absolute intensity of a weak magnetic field is described. We used a superconducting material as a sensor and detected its magnetization change between the superconducting state and the normal state at the transition temperature, The magnetization change measured by the SQUID

โฆ Synopsis
Measurements of the real pert of the input impedance of a RF biased SQUID are dascdbed. The experimental data are in good agreement with the predictions of the recently pub//shed theory. In particular the dependence of the input resistance on the detuning of the rf bias frequency from tank circuit resonance frequency is confirmed.
