The heat treatment effect of the magnetostrictive component in magnetoelectric (ME) composites consisting of a piezoelectric and magnetostrictive material has been studied. The dependence of the ME voltage coefficient on frequency was experimentally found without heat treatment and with annealing from 200 to 500°C of the AMAG493 amorphous alloy, which acted as a magnetostrictive component. It is shown that with an increase in the processing temperature of an amorphous alloy, an increase in the ME voltage coefficient is observed: the maximum value of the ME coefficient was observed at a temperature of 350°C and amounted to 29.52 V cm

at a resonance frequency of 54 kHz. It has been proven that the increase in the ME voltage coefficient occurs due to the improvement in the characteristics of the amorphous alloy during heat treatment, which leads to partial nanocrystallization of the material.
