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…
A direct measurement of the Bose-Einstein Condensation universality class in NiCl-4SC(NH) at ultra-low temperatures
L. Yin, J. S. Xia, V. S. Zapf +2
In this work, we demonstrate field-induced Bose-Einstein condensation (BEC) in the organic compound NiCl-4SC(NH) using AC susceptibility measurements down to 1 mK. The…
Spin Dynamics of in the Field-Induced Ordered Phase
S. A. Zvyagin, J. Wosnitza, A. K. Kolezhuk +6
- (known as DTN) is a spin-1 material with a strong single-ion anisotropy that is regarded as a new candidate for Bose-Einstein condensation (BEC) of spin deg…
Bose-Einstein condensation in antiferromagnets close to the saturation field
D. Reyes, M. A. Continentino, A. Paduan-Filho
At zero temperature and strong applied magnetic fields the ground sate of an anisotropic antiferromagnet is a saturated paramagnet with fully aligned spins. We study the quantum ph…
