I. Sugitani,Yusuke Okuda,Hiroaki Shishido,Tsutomu Yamada,Arumugam Thamizhavel,Etsuji Yamamoto,Tatsuma D. Matsuda,Yoshinori Haga,Tetsuya Takeuchi,Rikio Settai,Yoshichika Ōnuki,Yoshichika Ōnuki +11 more
TL;DR: In this paper, pressure-induced superconductivity was found in an antiferromagnet CeIrSi 3, which lacks inversion symmetry in the tetragonal crystal structure.
Journal ArticleDOI
Nonunitary Spin-Triplet Superconductivity in UPt3 : Evidence from 195Pt Knight Shift Study
Hideki Tou,Yasuo Kitaoka,K. Ishida,Kunisuke Asayama,Noriaki Kimura,Yoshichika Ōnuki,Yoshichika Ōnuki,E. Yamamoto,Yoshinori Haga,Kunihiko Maezawa +9 more
TL;DR: In this article, a spin-triplet odd-parity superconductor with a nonunitary spin-parallel spin pairing was shown to have a two-component ρ-vector with a superconducting transition temperature of 28 mK, regardless of major crystal orientations.
Journal ArticleDOI
Odd-Parity Superconductivity with Parallel Spin Pairing in UPt3 : Evidence from 195Pt Knight Shift Study
Hideki Tou,Yasuo Kitaoka,Kunisuke Asayama,Noriaki Kimura,Yoshichika Ōnuki,Yoshichika Ōnuki,E. Yamamoto,Kunihiko Maezawa +7 more
TL;DR: It is demonstrated that UPt{sub 3} is the odd-parity superconductor following the direction of the magnetic field in a range of 4.4{endash}15.6kOe without an appreciable pinning of the order parameter to the lattice.
Journal ArticleDOI
Coherent Kondo State in a Dense Kondo Substance: CexLa1-xCu6
TL;DR: In this paper, the electrical resistivity, magnetoresistance and magnetic susceptibility of single crystalline Ce x La 1-x Cu 6 ( x = 0-1) have been measured down to mK region.
Journal ArticleDOI
Recent Advances in Ce-Based Heavy-Fermion Superconductivity and Fermi Surface Properties
TL;DR: In this paper, the recent advances in Ce-based heavy fermion superconductivity were presented, where the competition between the Ruderman-Kittel-Kasuya-Yosida interaction and the Kondo effect was considered.
