| Outline of Final Research Achievements |
We have developed the magnetic measurement system at extremely high pressure using SQUID. In the style of using commercial SQUID magnetometer, we considered the change in the material of a diamond anvil cell, so that we constructed the precise magnetization measurement system. And, we developed the coil-vibrating SQUID magnetometer to detect the magnetization precisely in the lock-in style as well.
These techniques were used in the measurements of the Nd2Fe14B permanent magnets, cuprate superconductors, organic ferromagnets, solid oxygen, and so on. And, so as to realize further increase in the superconducting transition temperature Tc of the single-element superconductors, we conducted the high-pressure experiments for their severe deformed superconductors. Furthermore, in cuprate superconductors such as Y-124 and Hg-1223, we studied the ideal structure-modification for increasing Tc effectively.
