Spin susceptibility tensor of a thin film Weyl fermion structure is investigated theoretically. In the current study
Kubo–Streda approach have been employed by taking into account the vertex corrections, for studying the
influence of the vertex corrections on the magnetic response function of a thin film Weyl fermion. In this case
the effect of impurity interactions is captured within the Born approximation based Green’s function formalism.
Moreover the influence of successive impurity scatterings of electron hole pairs is given by the vertex diagrams
within the Bethe–Salpeter equation. Using this approach it was revealed that the vertex corrections decrease
spin–spin correlations in this type of the samples.
