Magnetic measurements were made up to 40 kHz using a custom made amorphous yoke. Magnetostrictive characterization was performed with prestress up to 15 Mpa in quasi-static and dynamic conditions (up to 40 Hz). A maximum deformation of about 6 x 10(-4), producing work, can be achieved with a variable phenol content. Dynamic magnetic properties were simulated using the dynamic Preisach model, obtaining an estimate value for conductivity. The inclusion of a non-conductive phenol binder increases the mechanical strength and favors a reduction of eddy current losses, for applications at sonic or ultrasonic frequency.
