Journal ArticleDOI
Presumption for a Quantum Energy Gap in the Quasi-One-Dimensional S?=?1 Heisenberg Antiferromagnet Ni(C2H8N2)2NO2(ClO4)
TL;DR: In this article, magnetic susceptibility and inelastic neutron scattering experiments have been performed in the nearly ideal one-dimensional Heisenberg antiferromagnet with spin one, Ni(C2H8N2)2NO2ClO4.
Journal ArticleDOI
Neutron Scattering from Magnetic Excitations in Bi_2 Sr_2 Ca_2 O_8+delta
H. F. Fong,P. Bourges,Y. Sidis,L. P. Regnault,Alexandre Ivanov,G. D. Gu,N. Koshizuka,Bernhard Keimer +7 more
TL;DR: In this paper, a magnetic resonance peak in the superconducting state of a different copper oxide system, Bi_2 Sr_2 Ca Cu_2 O(8+δ) was found.
Journal ArticleDOI
Quantum energy gap in two quasi‐one‐dimensional S=1 Heisenberg antiferromagnets (invited)
J.P. Renard,M. Verdaguer,L. P. Regnault,W. A. C. Erkelens,J. Rossat-Mignod,J. Ribas,W. G. Stirling,C. Vettier +7 more
TL;DR: In this paper, the authors provided an approximate value for the energy gap: EG≂0.4/k ≈−50 K, where J is the intrachain exchange interaction, which is consistent with the Haldane conjecture.
Journal ArticleDOI
Magnetic Resonant Mode in the Single-Layer High-Temperature Superconductor Tl2Ba2CuO6+δ
H. He,P. Bourges,Yvan Sidis,Clemens Ulrich,L. P. Regnault,Stéphane Pailhès,N. S. Berzigiarova,N. N. Kolesnikov,Bernhard Keimer +8 more
TL;DR: In this article, it was shown that the resonant mode is present in Tl2Ba2CuO6+δ, a single-layer compound with a superconducting transition temperature of ∼90 kelvin, demonstrating that it is a generic feature of the copper oxide superconductors.
Journal ArticleDOI
Neutron and magnetization studies of CeSb and CeSb1−xTex solid solutions
J. Rossat-Mignod,J.M. Effantin,P. Burlet,T. Chattopadhyay,L. P. Regnault,H. Bartholin,C. Vettier,O. Vogt,D. Ravot,J.C. Achart +9 more
TL;DR: In this article, the unusual properties of CeSb are reviewed and new results presented, in particular the magnetic phase diagram has been investigated under high magnetic fields where a new phase FP′ (+++0) has been discovered and under high pressure which increases strongly TN (TN = 30.5 K at P = 21 kbar), changes the ordering to type I and suppresses the non-magnetic planes.
