D.Gitsu, T.Huber, L.Konopko, A.Nikolaeva. Peculiarities Of Longitudinal Magnetoresistance In Single Crystal Wires Of Pure And Doped Bismuth. P.41-51.
Some regularities of the galvanomagnetic size effect (GMSE) manifestation on the longitudinal magnetoresistance DR/R (LM) in thin Bi wires at variation of the energy spectrum parameters of the charge carriers by doping with acceptor and donor impurities and strong stretching were studied (H < 140 kOe, T = 4.2K). It is clear shown that in the initial magnetic field (H) range the LM main: characteristic peculiarities: the maximum presence at rL~d (rL is the Larmor radius, d is the wire diameter), and the absence of LM (DR/R ~ 0) at rL>= d are determined by the number and localization of the actual energetic extremes and by orientation of the isoenergetic surfaces to the wire axis. In the region of quasi-classical strong magnetic fields (rL << d) the LM changes approximately as R(H) ~ Ha where a ~ l for pure Bi and is about 1/2 if only T-holes take part in transport processes. For the latter case the Larmor radius determined from the conditions of the LM saturation is rL~ d/2.
