The piezomagnetic properties of rapidly quenched Fe73.5Cu1Nb3Si13.5B9 alloy strips were investigated in as-quenched state and after annealing for 1 h in vacuum in the temperature range from 300°C to 600°C. The saturation magnetostriction was equal to about 25 × 10−6 for as-quenched state and after annealings to 480°C and next decreased to nearly zero after annealing at 550°C. The magnetomechanical coupling coefficients increased from 0.1 to 0.72 after annealing at temperature range from 440°C to 470°C. The elasticity modulus varied from 58 to 170 to 200 GPa (after crystallization).
