Weakly coupled alternating S=12 chains in the distorted honeycomb lattice compound Na2Cu2TeO6
Spin-1/2 chains with alternating antiferromagnetic (AF) and ferromagnetic (FM) couplings exhibit quantum entanglement like the integer-spin Haldane chains and might be similarly utilized for quantum
Phonon excitations in the quasi-one-dimensional Haldane phase of SrNi2V2O8
Vibrational Raman spectra of a single crystal of the coupled Haldane chain compound SrNi2V2O8 with uniaxial anisotropy were investigated in the 10–1000 cm−1 frequency range at temperatures 7–300 K.
Size reduction-induced chain breaking in Haldane-chain compounds SrNi2−xMgxV2O8 (x  =  0 and 0.1)
The size reduction-induced chain breaking in the spin-1 Haldane-chain SrNi2-x Mg x V2O8 is reported by magnetization and electron spin resonance measurements, implying that a reduced sample grain size breaks the long chain and creates a considerable number of S’  =” 1/2 edge spins, resulting in the enhancement of Magnetization and the decrease ofHaldane gap in the samples.
Near-ideal molecule-based Haldane spin chain
The molecular coordination complex NiI$_2$(3,5-lut)$_4$ [where (3,5-lut) $=$ (3,5-lutidine) $=$ (C$_7$H$_9$N)] has been synthesized and characterized by several techniques including synchrotron X-ray
