The effect of mechanical tensile stresses 0 = S = 62 MPa on the low-field (0 = H = 45 Oe) magnetization curves of the metallic glasses Fe_{100 - x}B_x (x = 14, 16, 17, 20) is studied at temperatures of 77 and 300 K. The correlation between the electronic structure of the glasses and their magnetostrictive sensitivity k_s is revealed: the eutectic metallic glass Fe₈₃B₁₇, which possesses a special electronic structure with a 30 % lower conduction (sp) electron density, has a value of k_s differing substantially from that of the other metallic glasses studied. Under low stresses (0 = S = 22 MPa) the eutectic alloy possesses a magnetostrictive sensitivity k_s(S₁) which is higher than that of the rest of the alloys studied, while under high stresses (22 MPa = S = 62 MPa) its magnetostrictive sensitivity k_s(S₂) is close to zero.
