This chapter introduces the field of molecular magnetism with a brief overview of the main properties. It takes a historical point of view. Concepts such as magnetic anisotropy, superparamagnetism, and magnetic relaxation, which are the keys to understanding how the bulk behaviour arises from nanomagnetism, are discussed first. The concept of single molecule magnet is introduced next, with the coexistence of classical and quantum effects, such as magnetization tunnelling and oscillation of the tunnel splitting. The last part of the chapter is devoted to describing the structure of the book, indicating the content of the various chapters.

Keywords:   nanomagnetism, single molecule magnets, molecular magnetism, magnetic anisotropy, superparamagnetism, ising, quantum tunnelling, tunnel splitting
