Abstract
The work is devoted to investigation of longitudinal magnetoresistance (LM) of Bi wires in dependence on diameter and actuality of energy extremes. Doping and elastic stretching of wires allowed to realize different types of electron topologic transitions. In the initial range of magnetic fields the LM has 2 characteristic peculiarities: a) the maximum presence at r c ≃ d/2 (r c is cyclotron radius, d is the wire diameter), b) the absence of LM. It was established that the maximum presence on the LM is determined by availability and anisotropy of L-carriers and galvanomagnetic size effect (GMSE). The absence of LM in initial magnetic field and negative LM (R ∼ H -1/2 ) with following saturation at r L ∼ d/2 in the strong magnetic field is typical for samples where conductivity is realized only by T-holes and completely corresponds to the Chambers-Azbel theory for isotropic dispersion law and diffusive scattering of carriers by surface.
