THEORY OF MAGNETIC-BREAKDOWN OSCILLATIONS OF THE GALVANOMAGNETIC PROPERTIES OF ALUMINUM TAKING ACCOUNT OF THE SPIN OF THE CONDUCTION ELECTRONS

The theory of magnetic breakdown, taking account of the spin of the co nduction electrons, is used to calculate the galvanomagnetic propertie s of aluminum, where the system of electron trajectories in a magnetic field contains small beta orbits. Expressions are obtained for the ma gnetoresistance and Hall resistance in the case of a two-dimensional m agnetic-breakdown network of trajectories on the basis of stochastic e lectron motion on large orbits and coherent electron motion on the bet a orbits. Qualitative agreement is obtained with the existing experime ntal data. (C) 1997 American Institute of Physics.
