Query: Low-dimensional quantum magnetism in Cu(NCS)$_2$: A molecular framework
  material   Low-dimensional magnetic materials with spin-$\frac{1}{2}$ moments can host a
range of exotic magnetic phenomena due to the intrinsic importance of quantum
fluctuations to their behavior. Here, we report the structure, magnetic
structure and magnetic properties of copper(II) thiocyanate, Cu(NCS)$_2$, a
one-dimensional coordination polymer which displays low-dimensional quantum
magnetism. Magnetic susceptibility, electron paramagnetic resonance (EPR)
spectroscopy, $^{13}$C magic-angle spinning nuclear magnetic resonance (MASNMR)
spectroscopy, and density functional theory (DFT) investigations indicate that
Cu(NCS)$_2$ behaves as a two-dimensional array of weakly coupled
antiferromagnetic spin chains ($J_2 = 133(1)$ K, $\alpha = J_1/J_2 = 0.08$).
Powder neutron-diffraction measurements confirm that Cu(NCS)$_2$ orders as a
commensurate antiferromagnet below $T_\mathrm{N} = 12$ K, with a strongly
reduced ordered moment (0.3 $\mu_\mathrm{B}$) due to quantum fluctuations.
