Magnetic crossover and complex excitation spectrum of the ferromagnetic/antiferromagnetic spin-1/2 chain system alpha-TeVO4
V. Gnezdilov, P. Lemmens, A. A. Zvyagin +5
We report magnetic susceptibility, specific heat, and Raman scattering investigations of alpha-TeVO4 containing V-O edge-sharing chains. These chains promote a system of ferromagne…
Character of magnetic excitations in a quasi-one-dimensional antiferromagnet near the quantum critical points: Impact on magneto-acoustic properties
O. Chiatti, A. Sytcheva, J. Wosnitza +5
We report results of magneto-acoustic studies in the quantum spin-chain magnet NiCl-4SC(NH) (DTN) having a field-induced ordered antiferromagnetic (AF) phase. In the vi…
Magnetic ordering of weakly coupled frustrated quantum spin chains
A. A. Zvyagin, S. -L. Drechsler
The ordering temperature of a quasi-one-dimensional system, consisting of weakly interacting quantum spin-1/2 chains with antiferromagnetic spin-frustrating couplings (or zig-zag l…
Evolution of the Kondo state of YbRh2Si2 probed by high field ESR
U. Schaufuß, V. Kataev, A. A. Zvyagin +6
An electron spin resonance (ESR) study of the heavy fermion compound YbRh2Si2 for fields up to ~ 8 T reveals a strongly anisotropic signal below the single ion Kondo temperature T_…
