ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase
M. Ozerov, M. Maksymenko, J. Wosnitza +6
Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…
Magnetic excitations in the spin-1 anisotropic antiferromagnet
C. Psaroudaki, S. A. Zvyagin, J. Krzystek +3
The spin-1 anisotropic antiferromagnet NiCl_2-4SC(NH2)_2 exhibits a field-induced quantum phase transition that is formally analogous to Bose-Einstein condensation. Here we present…
Magnetic properties of the Haldane-gap material NENB
E. Cizmar, M. Ozerov, O. Ignatchik +9
Results of magnetization and high-field ESR studies of the new spin-1 Haldane-chain material [Ni(C2H8N2)2NO2](BF4) (NENB) are reported. A definite signature of the Haldane state in…
Magnetic Excitations in the Spin-1 Anisotropic Heisenberg Antiferromagnetic Chain System NiCl-4SC(NH)
S. A. Zvyagin, J. Wosnitza, C. D. Batista +7
NiCl-4SC(NH) (DTN) is a quantum S=1 chain system with strong easy-pane anisotropy and a new candidate for the Bose-Einstein condensation of the spin degrees of freedom.…
High Magnetic Field ESR in the Haldane Spin Chains NENP and NINO
M. Sieling, U. Löw, B. Wolf +3
We present electron spin resonance experiments in the one-dimensional antiferromagnetic S=1 spin chains NENP and NINO in pulsed magnetic fields up to 50T. The measured field depend…
