We find that the measured temperature dependence of the local susceptibility agrees with bulk. No temperature dependence is observed below 200\&$\#$xa0;mK, indicating that at these temperatures the V 15 molecular spin resides in its S = 1 2 ground state.}, keywords = {Knight shift}, issn = {0921-4526}, doi = {http://dx.doi.org/10.1016/j.physb.2008.11.106}, url = {http://www.sciencedirect.com/science/article/pii/S0921452608006261}, author = {Z.
