MagnetismDiamagnetism, paramagnetism, ferromagnetism, ferrimagnetism, and antiferromagnetism will be discussed. These are described in the magnetism chapters of Kittel (chapters 11 and 12) and chapter 12 of festkörperphysik by R. Gross und A. Marx. Kittel describes magnetism mostly phenomenologically. He gives formulas for magnetic properties without deriving them rigorously. We will consider diamagnetism and paramagnetism using statistical physics similar to the discussion in Gross and Marx. To describe ferromagnetism, ferrimagnetism, or antiferromagnetism we will have to include exchange which arises from the Pauli exclusion principle and the Coulomb interaction between the electrons.
