Abstract

Hydrogenation effects on crystalline and magnetic structure of nanocomposites (FeCoZr) x (Al2O3) 100-x, 38 le;x≤63 at.% are studied by 57Fe Mössbauer spectroscopy and magnetometry. Variations of local structure, blocking temperature and mean FeCoZr nanoparticles' volume are discussed with respect to (i) composition and (ii) two competing processes-H2 incorporation and annealing-occurred during treatment in H2 plasma.
