The diamagnetism of platinum metals (N: Rh, Pt, Pd), which is induced by the proximity effect of a superconductor (S: Nb), has been investigated for N-S double layers. Notwithstanding the strong spin fluctuation in platinum metals, the screening d...

The Josephson effect between the spin-triplet superconductor Sr2RuO4 and conventional superconductors has been investigated for Sr2RuO4/Nb and Sr2RuO4/Sn junctions, which are fabricated on the cleaved (0 0 1) plane of single-crystalline Sr2RuO4, C...

Maximum supercurrent I(c) passing through S(Nb)-N(Cu doped with Mn)-S(Nb) proximity system has been measured down to 30 mK, in order to investigate the relation between the superconducting proximity effect and the Kondo effect. It is found that I(...
We have performed parallel measurements of dc-magnetization and ac-magnetic susceptibility for a ferromagnetic superconductor, UGe2, in the ferromagnetic-superconducting phase. dc-magnetization measurements revealed that adequate demagnetizing of ...

We performed dc-magnetization and ac-susceptibility measurements to clarify how the magnetic properties of CeAgSb2, which shows ferromagnetic order along the c-axis below 9.6 K, evolve with the application of a transverse magnetic field (H-ab). Th...
