摘要：

A pulse field magnetometer with a new flat pick-up coil device is presented for the characterization of magnetic materials in high magnetic fields. The dimensions of this pick-up coil allow the registration of local hysteresis loops. Magnetization measurements and anisotropy field measurements were performed locally on Nd-Fe-B and M-type ferrite permanent magnets at room temperature. Estimation of the local demametizing factor by the measurement of H-A using the SPD technique is presented. Local hysteresis loops show the eddy current effect in conducting magnetic metallic samples. The field calibration with the surface coil is also discussed. (C) 2003 Elsevier B.V.
