Abstract A study of magnetic breakdown between the third zone needles and second zone monster surfaces in the three zinc alloy systemsZnMn,ZnCr, andZnFe shows that the tunneling probability is strongly reduced by electron scattering and that the breakdown fieldH 0 increases linearly with the Dingle temperatureX with a scaling factor of 0.36 kG/K for all alloys. This phenomenon may be understood if we allow the electrons to be scattered during their tunneling through the forbidden region ofk space. A simple semiclassical calculation of this effect yields an expression for the breakdown probability corrected from the conventional expression toP=exp[−(1/H)(H0+αX)], where α is a constant dependent only on the band structure of the solvent.
