Abstract

The problem of the galvanomagnetic properties of composite materials is formulated for a lattice model. The effective galvanomagnetic characteristics of a weakly heterogeneous lattice are determined in the quadratic approximation in the deviation of local conductivity tensor \(\hat \sigma \) (r) from average value <\(\hat \sigma \)>. In the case of a low concentration (c ≪ 1) of “defect” bonds, effective conductivity tensor \(\hat \sigma \) e of a binary lattice model is calculated in the c-linear approximation. Effective medium method equations are derived for the formulated lattice problem, and the results are compared with the results obtained in a continuous medium model.
