For the past few years,the discovery of iron-based superconducting materials raised a hot wave of new superconducting material research.Many kinds of iron-based superconducting materials were successfully manufactured and their transition temperature continuously increasing either.Chinese scientists in this field have achieved prominent results and manufactured a lot of iron-based superconducting materials,but their AC loss characteristics which are very important in practical applications are rarely reported.For measuring the hysteresis loss of iron-based superconducting materials,a set of AC loss measurement platform was created employing the pick-up coil method.Which contains pick-up coil,compensation coil,compensation circuit,specimen form,AC superconducting magnet,low-frequency AC power,cryostat,amplifiers and data acquisition system.The AC loss measurement platform comply with IEC standardwith which the AC loss of a kind of single-core iron-based superconducting tape made by Institute of Electrical Engineering of Chinese Academy of Sciences with PIT process was measured.This paper describes the set-up and calibration of the measuring platform used for AC loss measurement of superconducting materials with pickup-coil method and the AC loss measurement of iron-based superconducting tape with single core manufactured by PIT process using the calibrated AC loss measurement platform at liquid helium temperature 4.2K.Compared with the calculating results of hysteresis loss of single core and eddy current loss of iron sheath of the iron-based on-based superconducting tape,it shows that its AC loss is directly proportional to the frequency of AC background magnetic field and its eddy current loss can be neglected.
