| Abstract: | A measurement of the Curie temperature for the ferromagnetic meterial pressed by the piston in a cylindric pressure vessel. The system has higher sensitivity so that the small samples could be measured, though it consists only of simple measuring circuits and without precise instruments such as the phase lock amplifier. The measurement turns out a success due to the reasonable configuration for getting high pressure. The measurement data show that the repetability error is less than ±1 ℃. |
