Pakulis and Jeffries first observed Zeeman transitions in germanium crystals which they attributed to the grown‐in dislocations. The authors explained the effect as a change of the electrical conductivity of the crystal due to spin dependent scattering of the carriers. The spin flip was ascribed to dislocation dangling bonds. Using plastically deformed germanium we can show that the signal is due to combined resonance of conduction electrons in one valley of the conduction band the energy of which is lowered by the strain field of dislocations. Additionally two more combined resonance lines are identified which also are assigned to the glide geometry. The delocalised states of electrons causing these lines by spin flip are not yet determined.
