SYMMETRY PROPERTIES OF WAVE FUNCTIONS IN MAGNETIC CRYSTALS
Abstract
The symmetry properties of wave functions in magnetic crystals are discussed in terms of the irreducible representations of magnetic space groups. The specific effects of the magnetic ordering on the crystal eigenstates are of three types: (1) There is a lifting of some eigenfunction degeneracies because the crystal symmetry is reduced in the magnetic state; (2) New Brillouin zone surfaces are introduced if there is a reduction in translational symmetry; (3) The symmetry of the energy band in K-space may be reduced. The rutile structure is considered as a specific example and the space groups of MnF2 and MnO2 in their magnetic and nonmagneti states are obtained. (Author)
