Dislocation scattering and de Haas-van Alphen effect

The Dingle temperature (describing the scattering strength in a magnetic field) of edge dislocations in metals is calculated in the free-electron model by introducing an outer cut off radius equal to the cyclotron and orbit radius. No limiting scattering angle has to be considered. A more general approach involving magnetic-field-dependent wave-functions leads directly to a field-dependent Dingle temperature.
