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
Destruction of the Kondo effect in the cubic heavy-fermion compound Ce3Pd20Si6
J. Custers,K. A. Lorenzer,Markus Müller,Andrey Prokofiev,Andrey Sidorenko,H. Winkler,André M. Strydom,Yasuyuki Shimura,Toshiro Sakakibara,Rong Yu,Qimiao Si,Silke Paschen +11 more
TL;DR: A cubic heavy-fermion material is identified as exhibiting a field-induced quantum phase transition, and it is shown how the material can be used to explore one extreme of the dimensionality axis, leading to a materials-based global phase diagram.
Journal ArticleDOI
Magnetocaloric effect and magnetic cooling near a field-induced quantum-critical point.
Bernd Wolf,Yeekin Tsui,D. Jaiswal-Nagar,Ulrich Tutsch,Andreas Honecker,Katarina Remović-Langer,Georg Hofmann,Andrey Prokofiev,Wolf Assmus,Guido Donath,Michael Lang +10 more
TL;DR: In this paper, the authors determined the critical enhancement of ∆S/∆B near a B-induced QCP via absolute measurements of the magnetocaloric effect (MCE), (∆T/∂B)S and demonstrate that the accumulation of entropy around the QCP can be used for efficient low-temperature magnetic cooling.
Journal ArticleDOI
Crystallographic and magnetic structure of ZnV $\mathsf{_2}$ O $\mathsf{_4}$
TL;DR: In this paper, the structure of the geometrically frustrated spinel ZnV2O4 was determined by neutron powder diffraction at T = 51 K, where a cubic-to-tetragonal phase transition takes place.
