Symmetry principles and magnetic symmetry in solid state physics

Part 1 Introduction to symmetry principles in solid state physics: elements of symmetry theory elementary theory of group representation important properties of the irreducible representation of crystal symmetry groups symmetry in the crystalline state the three-dimensional rotation group illustrative examples of the applications of symmetry principles. Part 2 Symmetry and the magnetic state: classification of magnetic materials construction of magnetic groups co-representation of magnetic groups symmetry properties of wavefunctions in magnetic crystals space-group selection rules for magnetic crystals.
