Fig. 2. (a, c and e) Positron lifetime components vs. the mean penetration depth (i.e., implantation energy, Ep) for the different magnetic states of the film obtained from Bath 1 (as-deposited), the same film subject to annealing in air (as-annealed), and the annealed film voltage-treated at −20 V for 30 min (gated). (b, d and f) Symbolize the relative intensities of each of the defect size ranges, for the magnetic states studied. For lifetimes larger than 500 ps ortho-positronium annihilation contributions in micropores is expected. The respective lifetimes were recalculated to the pore sizes and given as the right Y-axis.38.
