英文摘要
We have succeeded in measuring the Josephson effect of UP_<t3> in the superconducting C phase for the first time by applying pressure and making the C phase appear in low magnetic fields, and found no qualitative difference between the B and C phases. The point-contact spectroscopy of UR_<u2> S_<i2> under pressure suggests that the "hidden order" phase and antiferromagnetic phase has a similar electronic state near the Fermienergy.
