Low Temperature Thermal and Magnetic Properties of Cu-Doped Haldane Gap Antiferromagnet NENP
TL;DR: In this paper, the effects of Cu-impurity on the Ni 2+ (S = 1)-chain were studied by heat capacity and susceptibility measurements down to 30 mK on the Haldane-gap antiferromagnet Ni(C 2 H 8 N 2 ) 2 NO 2 (ClO 4 ) (NENP).
Journal ArticleDOI

Shingo Araki,Minami Hayashida,Naoto Nishiumi,Hiroki Manabe,Yoichi Ikeda,Tatsuo C. Kobayashi,Keizo Murata,Yoshihiko Inada,Piotr Wiśniewski,Piotr Wiśniewski,Dai Aoki,Yoshichika Ōnuki,Yoshichika Ōnuki,Etsuji Yamamoto,Yoshinori Haga +14 more
TL;DR: In this article, the authors investigated the pressure-temperature-field phase diagram and quantum fluctuation effect in the itinerant ferromagnet U3P4 by resistivity, ac susceptibility, and Hall effect measurements under high pressure.
Journal ArticleDOI
Pressure and magnetic field tuned quantum critical point in the Kondo antiferromagnet CePtZn.
S. K. Dhar,Ruta Kulkarni,H. Hidaka,Y Toda,Hisashi Kotegawa,Tatsuo C. Kobayashi,Pietro Manfrinetti,Alessia Provino +7 more
TL;DR: It is found that CePtZn is a dense Kondo lattice, ordering antiferromagnetically at T(N) = 1.7 K, with a comparable Kondo temperature, and logarithmic divergence of the heat capacity at 6 T in a limited temperature region strongly suggest the emergence of a quantum critical point.
Journal ArticleDOI
Magnetization study of heavy Fermion superconductor URu2Si2 under high pressures
Kenichi Tenya,Ikuto Kawasaki,K. Tameyasu,Shingo Yasuda,Makoto Yokoyama,Hiroshi Amitsuka,N. Tateiwa,Tatsuo C. Kobayashi +7 more
TL;DR: In this paper, the superconducting transition temperature decreases linearly with pressure up to 1.1 GPa and disappears above 1.5 GPa, suggesting that the pinning properties are changed due to the switch of the normal state to the antiferromagnetic state.
