Abstract: Nanometer scale is introduced in the well-known Haldane system $$\hbox {Y}_{2}\hbox {BaNiO}_{5}\,(S=1)$$Y2BaNiO5(S=1). Magnetization and pulsed-field electron spin resonance (ESR) measurements were performed. As a result, the magnetization of nanoparticles is much enhanced as compared with… read more here.

DOI: 10.1103/physrevb.102.014447
Abstract: Using a matrix product state algorithm with infinite boundary conditions, we compute high-resolution dynamic spin and quadrupolar structure factors to explore the low-energy excitations of isotropic bilinear-biquadratic spin-1 chains. Haldane mapped the spin-1 Heisenberg antiferromagnet… read more here.
