  We employ NMR techniques to investigate the nature of Mn spins in the I-II-V
diluted magnetic semiconductor Li(Zn1-xMnx)P (x = 0.1, Curie temperature Tc =
25 K). We successfully identify the 7Li NMR signals arising from the Li sites
adjacent to Mn2+, and probe the static and dynamic properties of Mn spins. From
the NMR spin-lattice relaxation data, we show that the Mn spin-spin
interactions extend over many unit cells.
