Abstract
Spin dependent attenuation lengths (AL) as a function of the hot electron energy are calculated for Fe, Co, and Ni. If λ 1(λ1) is the AL of an electron with spin parallel (antiparallel) to the majority spin direction of the ferromagnet then the quantity A = (λ1 - λ1)/(λ1 + λ1) is found to change sign as a function of the electron energy.
