Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4
B. Thielemann, Ch. Rüegg, K. Kiefer +18
Neutron diffraction is used to investigate the field-induced, antiferromagnetically ordered state in the two-leg spin-ladder material (Hpip)2CuBr4. This "classical" phase, a conseq…
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…
Thermodynamics of the Spin Luttinger-Liquid in a Model Ladder Material
Ch. Rüegg, K. Kiefer, B. Thielemann +11
The phase diagram in temperature and magnetic field of the metal-organic, two-leg, spin-ladder compound (C5H12N)2CuBr4 is studied by measurements of the specific heat and the magne…
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…
Using magnetostriction to measure the spin-spin correlation function and magnetoelastic coupling in the quantum magnet NiCl-4SC(NH)
V. S. Zapf, V. F. Correa, P. Sengupta +9
We report a method for determining the spatial dependence of the magnetic exchange coupling, , from magnetostriction measurements of a quantum magnet. The organic Ni …
Magnetostriction in the Bose-Einstein Condensate quantum magnet NiCl2-4SC(NH2)2
V. S. Zapf, V. F. Correa, C. D. Batista +6
The quantum magnet NiCl-4SC(NH) is a candidate for observing Bose-Einstein Condensation of spin degrees of freedom in applied magnetic fields. An XY antiferromagnetic o…
