| Abstract: | his paper shows a multifunction system for measuring thermophysical properties of solid-state material in low temperature, which is controlled by IBM PC automatically. It can supply, one by one or four in one times, curves of resistance in low and high pressure, ac susceptibility(including real and imaginary components) and specific heat vs. temperature from 77 K to room temperature.The system is more convenient and can be finished more quickly than separated apparatus. It is very important for studying material properties in low temperature and very useful, especially, for the researches of high-Tc superconductivity. |
