| dc.description | The theory of AC magnetoresistance in inhomogeneous solids is developed using the effective-medium theory. Calculations are performed for systems which consist of random high- and low-conductivity regions. The weak magnetic field H is directed along the z axis. The effective conductivity changes Delta sigma <sub>m</sub><sup>xx</sup> and Delta sigma <sub>m</sub><sup>zz</sup> and the magnetoresistance Delta rho <sub>m</sub><sup>xx</sup> and Delta rho <sub>m</sub><sup>zz</sup> in both the low- and the high-frequency regions are calculated up to the H<sup>2</sup> approximation. The calculations show that, owing to inhomogeneities, plateaux of the finite values Delta sigma <sub>m</sub><sup>zz</sup> and Delta rho <sub>m</sub><sup>zz</sup> in the low-frequency region occur. It is possible to have both Delta rho <sub>m</sub><sup>xx</sup>> Delta rho <sub>m</sub><sup>zz</sup> and Delta rho <sub>m</sub><sup>xx</sup>< Delta rho <sub>m</sub><sup>zz</sup>. In the high-frequency limit the equalities Delta sigma <sub>m</sub><sup>zz</sup>= Delta rho <sub>m</sub><sup>zz</sup>=0 hold as in homogeneous solids. |
