Abstract: Magnetic field dependences of the piezomagnetic dynamics and the magnetomechanical coupling on the heat-treatment and magnetic bias field in the Fe62.5Co6Ni7.5Zr6Cu1Nb2B15 alloy strips were investigated. The magnetomechanical coupling coefficient increased from 0.10-0.12 for as-quenched samples to 0.38 after annealing at 390oC.
