I want to make a magnetostrictive ultrasonic transducer for homogenizing applications.
I also want to make its power supply by myself.
I need some references (papers, patents, reports, books videos, etc.) that can help me in this way.
I would appreciate your help

The ultrasonic piezoelectric transducer operates on the concept of the converse piezoelectric effect. When electricity is supplied to a piezoelectric material, it undergoes physical deformations that are proportional to the applied charge.
However, Magnetostrictive transducers are made up of a large number of nickel (or other magnetostrictive material) plates or laminations that are placed in parallel, with one edge of each laminate affixed to the bottom of a process tank or other vibrating surface. A wire coil is wrapped around the magnetostrictive material.
Ju Cheng, what is the frequency range you are interested in? For relatively low frequencies, say not more than few MHz, I would sugest to consider transducers based on terfenol or similar alloys with giant magnetostriction. There are certain tricks using it, like applying static stress or static magnetic field. Probably this paper may help:

And on your former question about using the generator for the piezoelectric transducer to drive the magnetostrictive one. For magnetostrictive transducer you need higher current, in contrast to the piexoelectric one, which provides high voltage. But this can be solved, by means of some voltage-current converter
