Bis(glycolato)copper(II) [Cu(HOCH2CO2)(2)] shows a structural phase transition around 220 K under cooling and 270 K under heating, and ferromagnetic ordering at 1.1 K. Deuterium substitution of the hydroxyl groups in it induced a large shift in th...

TMU INTERNATIONAL SYMPOSIUM ON NEW QUANTUM PHASES EMERGING FROM NOVEL CRYSTAL STRUCTURE 683 2016年
We have measured the magnetization of two noncentrosymmetric superconductors: Ir2Ga9 and CePt3Si using a SQUID magnetometer, neither of which has been tested for the time-reversal symmetry in the superconducting state. For Ir2Ga9, the magnetizatio...

The anomalous behavior of the heavy-fermion superconductor UBe13, which appears below the superconducting transition temperature T-c similar to 0.9 K, has been investigated by point-contact spectroscopy and the Josephson effect. An abrupt increase...
