This research includes prepare magnetostrictive compound at ratio x = (0.0, 1.0) by ceramic method at 1200 ℃ sintering temperature. studied some of structural properties by X-ray diffraction technique, and mechanical properties by Fourier-transform infrared FT-IR technique. This is to determine the speed and frequency of ultrasonic waves that's can be generated using the prepared compound.
The results show formation the cubic spinel structure of ferrite, and values of Average crystallite size at nm. We observed at ratio x = 1.0 increase in values of Average crystallite size, lattice parameter, and decrease in values of density, and Young's coefficient.
The results also showed the frequency of ultrasonic generated at the kHz and MHz ranges, the speed and frequency of the ultrasonic waves generated by are higher than the speed and frequency of the cobalt Ferrite .
