Abstract

A pulsed field magnetometer with maximum field of 120 kOe has been constructed. The pulsed field generated by a 18 kJ capacitor bank system combined with a pulsed coil was damped oscillation with the period of 10.12 ms. The specimen space was designed to heat up to 200 . by flowing hot N-2 gas. Magnetic hysteresis curve was measured by induction method during 10.12 ms of a pulsed duration from the first positive to the second positive peak. The accuracy of PFM is 2% within the space of +/-2 mm x 8 mm . at the center ofJ-coil.
