Influence of dislocations on the de Haas-van Alfven effect under magnetic breakdown conditions

The influence of dislocations on the amplitude of de Haas–van Alfven oscillations is studied. It is shown that a calculation of the Dingle factor of the harmonic corresponding to the j-th cooperative orbit can be carried out in terms of the “local Hamiltonian” H^(j)=H^0(j)+u(r) where H^0(j) is determined by the type of the j-th orbit, u(r) is the electron potential in a dislocation field (the coordinate r is a parameter, and u(r) is a c-number).
