Times Cited Count：116 Percentile：94.41(Physics, Multidisciplinary)Shubnikov-de Haas measurements of high quality URuSi single crystals reveal two previously unobserved Fermi surface branches in the so-called hidden order phase. Therefore, about 55% of the enhanced mass is now detected. Under pressure in the antiferromagnetic state, the Shubnikov-de Haas frequencies for magnetic fields applied along the crystalline c axis show little change compared with the zero pressure data. This implies a similar Fermi surface in both the hidden order and antiferromagnetic states, which strongly suggests that the lattice doubling in the antiferromagnetic phase due to the ordering vector 
= (001) already occurs in the hidden order. These measurements provide a good test for existing or future theories of the hidden order parameter.

Times Cited Count：127 Percentile：95.51(Physics, Multidisciplinary)Magnetoresistivity measurements with fine tuning of the field direction on high quality single crystals of the ferromagnetic superconductor UCoGe show anomalous anisotropy of the upper critical field 
. for 
-axis (
) in the orthorhombic crystal structure is strongly enhanced with decreasing temperature with an S-shape and reaches nearly 20 T at 0 K. The temperature dependence of 
shows upward curvature with a low temperature value exceeding 30 T, while 
at 0K is very small (
0.6 T).Contrary to conventional ferromagnets, the decrease of the Curie temperature with increasing field for 
-axis marked by an enhancement of the effective mass of the conduction electrons appears to be the origin of the S-shaped curve. These results indicate that the field-induced ferromagnetic instability or magnetic quantum criticality reinforces superconductivity.
