Abstract

A comparatively study of pulsed-laser and alpha particle irradiation effects in metallic glasses has been performed in order to understand the relationship between magnetic behavior and select variations in the structural characteristics of alloy phases. Samples of Fe₇₈B₁₃Si₉ and Fe₆₆Co₁₈B₁₅Si metallic glasses were irradiated with a pulsed excimer laser ((lambda) equals 308 nm, (tau) equals 10 ns) and alpha particle beams (W equals 2.8 MeV) using radiation doses of 10¹⁶ and 10¹⁷ cm^-2. Irradiation-driven changes in the magnetic anisotropy and phase equilibrium of alloy samples were studied by Mossbauer Spectroscopy and scanning electron microscopy. The evolution of phases and microstructure during the radiation- induced amorphous-to-crystalline transformations or revitrification depend on the specific irradiation and sample composition.
