corresponding to a crossover from the linear behavior to saturation of the negative magne- toresistance is given as Correspondingly, if H$_{min}$ given by Eq.22 appears to be larger than H$_{sat}$ our calculations given above are invalid and one should compare positive magnetoresistance with saturated negative magnetoresistance rather than with linear negative magnetoresistance. One notes that in contrast to linear magnetoresistance which is proportional to the area of the in- terference loop for the saturation magnetoresistance this proportionality is omitted. As a result, as it was noted above, the temperature dependence of the saturation value of nega- tive magnetoresistance Δ R$_{sat}$/R (0) results from factors ∝ r$_{h}$ for Mott hopping and ∝ r 1 / 2 h for the Coulomb gap hopping. It is seen that the corresponding increase of the saturation magnetoresistance with temperature decrease is much weaker than increase of the positive magnetoresistance. Then, in the case H$_{min}$ > H$_{sat}$ it is the value of H$_{sat}$ which corresponds to minimal resistance since it separates a region of resistance decrease due to negative mag- netoresistance and resistance increase due to positive magnetoresistance. However at this situation spin magnetoresistance (31) is also saturated so the temperature behavior of pos- itive magnetoresistance is related to (18) and (or) to (32). In its turn let us consider the temperature behavior of the relation between H$_{min}$ and H$_{sat}$ . According to Eq.22 and Eq.34 At the same time H$_{sat}$ ∝ T 1 / 2 for Mott law and H$_{s}$ ∝ T 3 / 4 for ES law. Thus the ratio H$_{min}$/H$_{sat}$ decreases with temperature decrease and this decrease is more pronounced for Mott law. At Fig.1 we present our experimental results from Ref. [6] for 3D hopping concerning temperature behavior of magnetoresistance for regimes of Coulomb gap hopping ( Fig. 1,a) and of Mott-type hopping (Fig. 1,b). It is seen that these results are in in a qualitative 15 V.
