Detection of a Disorder-Induced Bose-Einstein Condensate in a Quantum Spin Material at High Magnetic Fields
A. Orlova, H. Mayaffre, S. Krämer +5
The coupled spin-1 chains material NiCl-4SC(NH) (DTN) doped with Br impurities is expected to be a perfect candidate for observing many-body localization at high magnet…
Dynamics of Bound Magnon Pairs in the Quasi-One-Dimensional Frustrated Magnet LiCuVO_4
Kazuhiro Nawa, Masashi Takigawa, Steffen Krämer +4
We report on the dynamics of the spin-1/2 quasi-one-dimensional frustrated magnet LiCuVO measured by nuclear spin relaxation in high magnetic fields 10--34 T, in which…
Dichotomy between Attractive and Repulsive Tomonaga-Luttinger Liquids in Spin Ladders
M. Jeong, D. Schmidiger, H. Mayaffre +8
We present two methods to determine whether the interactions in a Tomonaga-Luttinger liquid (TLL) state of a spin- Heisenberg antiferromagnetic ladder are attractive or repuls…
Fermi Surface Reconstruction inside the Hidden Order Phase of URu2Si2 Probed by Thermoelectric Measurements
Alexandre Pourret, Alexandra Palacio-Morales, Steffen Kramer +5
We report thermoelectric measurements of the low carrier heavy fermion compound URu2Si2 at high fields up to 34T and at low temperatures down to 500mK. The field dependence of the…
Microscopic properties of the "pinwheel" kagome compound Rb_2Cu_3SnF_{12}
M. S. Grbić, S. Krämer, C. Berthier +4
Using Cu nuclear magnetic resonance (NMR) in magnetic fields up to 30 T we study the microscopic properties of the 12-site valence-bond-solid ground state in the "pinwhee…
High-field Phase Diagram and Spin Structure of Volborthite Cu3V2O7(OH)2/2H2O
Makoto Yoshida, Masashi Takigawa, Steffen Kramer +6
We report results of 51V NMR experiments on a high-quality powder sample of volborthite Cu3V2O7(OH)2/2H2O, a spin-1/2 Heisenberg antiferromagnet on a distorted kagome lattice. Foll…
