Abstract—This paper reports on a study of the specific features of photo- and thermostimulated exoelectronic
emission in amorphous metal alloys of Fe₆₄Co₂₁B₁₅ composition. The temperature dependences of the exoelec-
tronic emission spectrum were established to adequately reflect the two-stage nature of the transition of an
amorphous alloy to the crystalline state. The exoelectronic emission spectrum is sensitive to variations in the
thermal treatment to which the alloy is subjected. Thermal treatment of an amorphous metal alloy gives rise to
an increase in the exoelectron emission intensity. The growth in the exoelectron emission intensity was found
to be the highest for alloys in the initial stage of crystallization. © 2001 MAIK “Nauka/Interperiodica”.
