摘要：

Co-59 and La-139 NMR measurements were performed to study the spin state of the trivalent cobalt ion in LaCoO3 which exhibits the low-spin ((1)A(1g)) to high-spin (T-5(2g)) transition. It is pointed out that the supertransferred mechanism plays an important role in the magnetic hyperfine interaction of the high-spill state.
