From: Haldane topological spin-1 chains in a planar metal-organic framework
a Temperature dependence of the DC magnetic susceptibility (χ) of NiBO at 0.1 T. b Plot of \({{{{{\rm{ln}}}}}}[\chi \left({{{{{\rm{T}}}}}}\right)\mbox{--}\chi (0)]\) vs. 1/T for data below 11.5 K. c Temperature dependence of the DC susceptibility of NiBO at magnetic fields of 0.1-12 T.
