Classical antiferromagnetism inMnSc2S4: ASc45NMR study

${}^{45}\mathrm{Sc}$ NMR has been measured for the spinel compound $\mathrm{Mn}{\mathrm{Sc}}_2{\mathrm{S}}_4$. The Knight shift and the spin-lattice relaxation rate show typical behaviors expected for conventional localized moment systems. The Sc site separates into two different magnetic sites in the antiferromagnetic state below $T_N\simeq 2\mathrm{K}$, pointing to a simple spin structure. These results suggest that $\mathrm{Mn}{\mathrm{Sc}}_2{\mathrm{S}}_4$ is a rather conventional antiferromagnet.
