Abstract

A multilevel magnetic gradiometer is provided. The quantum wave effect caused by Josephson junction of the high critical temperature superconducting magnetic detecting device included in the multilevel magnetic gradiometer is used for measuring the change of the magnetic field, so as to increase the sensitivity of the High-Tc superconducting magnetic detecting device. The High-Tc superconducting magnetic detecting device of the present invention could further increase the safety and decrease the cost largely without the use of the traditional low temperature superconducting equipments. An accurate result could be obtained through the design of the pickup coils or comparing the signals read by a plurality of the High-Tc superconducting magnetic detecting devices. The multilevel magnetic gradient could be detected synchronously by the multilevel magnetic gradiometer in a non-shielding environment, so that the noise is filtered out and the micro-magnetic signal read thereby is analysed.
