75.60.Ch - Opis:
- Magnetic field dependences of the piezomagnetic dynamics, magnetomechanical coupling and elasticity moduli in the Fe$\text{}_{73.5}$Cu$\text{}_{1}$Nb$\text{}_{3}$ Si$\text{}_{13.5}$B$\text{}_{9}$ alloy in an as-quenched state and annealed in vacuum for 1 h at 450°C were investigated. The maximum value of the magnetomechanical coupling coefficient was equal to 0.15 for the as-quenched state and 0.7 after annealing at 450°C. The changes of the elasticity moduli (ΔE effect) from about 60 to 180 GPa were observed after annealing at this temperature. These changes are connected with magnetostriction (equal to 25.8×10$\text{}^{-6}$ at saturation), internal stresses, defects, mechanical, magnetic and heat treatment history.
