To investigate the elastic properties of solid He-4 at low temperatures, the shear modulus of solid He-4 confined in a narrow gap, comparable to the length of the dislocation network of solid He-4 was measured. Two sets of parallel plate transduce...

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...
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...

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...
Among many two-dimensional (2D) high T-C superconductors, graphite intercalation compounds (GICs) are the most famous intercalation family, which are classified as typical electron-phonon mediated superconductors. We show unambiguous experimental ...
