Journal ArticleDOI
Quantum helimagnetism of the frustrated spin-1/2 chain LiCuVO4
Mechthild Enderle,C. Mukherjee,B. Fåk,R. K. Kremer,Jean-Marc Broto,H. Rosner,S.-L. Drechsler,Johannes Richter,Jiří Málek,Andrey Prokofiev,Wolf Assmus,S. Pujol,J.-L. Raggazzoni,H. Rakoto,M. Rheinstädter,Henrik M. Rønnow +15 more
TL;DR: Inelastic neutron scattering, susceptibility, and high-field magnetization identify LiCuVO4 as a nearest-neighbour ferromagnetic, next-nearest-nighbour frustrated, quasi-one-dimensional helimagnet as discussed by the authors.
Journal ArticleDOI
Superconductivity in CeCu2Si2 Single Crystals
Wolf Assmus,M. Herrmann,U. Rauchschwalbe,S. Riegel,W. Lieke,H. Spille,Siegfried Horn,G. Weber,Frank Steglich,G. Cordier +9 more
TL;DR: Ce${\mathrm{Cu}}{2}$${\mathm{Si}}_{2}$ behaves as an $s$-state superconductor with strongly temperature-dependent pair breaking and almost isotropic Fermi surface as discussed by the authors.
Journal ArticleDOI
Breakup of heavy fermions on the brink of 'Phase A' in CeCu2Si2
Philipp Gegenwart,C. Langhammer,C. Geibel,R. Helfrich,Michael Lang,G. Sparn,Frank Steglich,R. Horn,L. Donnevert,A. Link,Wolf Assmus +10 more
TL;DR: In this article, the authors reported resistivity and specific heat properties on near stoichiometric samples in the vicinity of a quantum critical point (QCP) in the presence of heavy quasiparticles.
Journal ArticleDOI

TL;DR: In this paper, the structure of the β-phase has been redetermined at ambient temperature as well as in situ at 400°C, and the reciprocal space, Bragg and diffuse scattering, has been explored as a function of temperature and the β − to β −phase transition was studied in detail.
Journal ArticleDOI
Quantum critical phenomena in undoped heavy-fermion metals
Frank Steglich,B. Buschinger,Philipp Gegenwart,M. Lohmann,R. Helfrich,C. Langhammer,P. Hellmann,L. Donnevert,S. Thomas,A. Link,C. Geibel,Michael Lang,G. Sparn,Wolf Assmus +13 more
TL;DR: In this article, the authors present results of low-temperature calorimetric and resistive measurements on the isostructural heavy-fermion compounds and non-Fermi liquid effects, which suggest the nearness of an antiferromagnetic quantum critical point in both systems.
