| Outline of Final Research Achievements |
High precision SQUID magnetometer was developed, where we could measure DC magnetization and AC susceptibility even below 0.1 Hz of tiny samples down to a few tens mK. We achieved the sensitivity of 10-8 emu or higher for the DC measurements. In addition, we almost finalized the preparation of high pressure setup using a piston cylinder cell. This setup for high pressure high precision magnetization measurements will be quite useful for the studies of pressure induced quantum critical behavior and so on. On the other hand, using the set-up for ambient pressure measurements, the non-magnetic cage compound PrV2Al20, the chiral spin liquid compound Pr2Ir2O7 and the Kagome antiferromagnet Nd3Sb3Mg2O14 were studied.
