Paper presents the results of magnetoelastic tests of ring-shaped cores made of Fe_{40}Ni_{38}Mo_{4}B_{18} amorphous alloy. The cores were subjected to thermomagnetic annealing under different values of magnetic field. The obtained results enabled us to connect the magnetoelastic characteristics of Fe_{40}Ni_{38}Mo_{4}B_{18} amorphous alloy with the conditions of thermomagnetic treatment of the material.
