Summary

Single-molecule magnets (SMMs) are among the best materials for studies of nano-scale magnets. SMMs are located in the boundary region between the discrete atoms and the bulk magnets, and exhibit unusual classical and quantum magnetic properties such as meso-scale magnets. In this chapter, we will review the chemistry and physics of 12-nucleus Mn clusters (Mn12) as a SMM. After explaining the magnetization process and the quantum tunneling or coherence in Mn12, we will describe the magneto-structural correlation in Mn12, referring to the Jahn—Teller isomers of Mn12; a slight difference in structure at the Mn(III) site gives rise to a significant difference in magnetic relaxation. The possible application of SMMs is also described.
