Abstract

We characterized the magnetomechanical conversion abilities of Ni-Zn ferrite, cobalt ferrite, and Metglas by constructing a magnetic power path with two winding coils. We found that under high power drive, a portion of the mechanical power re-transformed to the magnetic form and was captured by the receiver coil, which resulted in a decrease in the magnetomechanical conversion ability of the coil-magnetostriction structure. This presents an upper limit of the power conversion characteristics of magnetoelectric gyrators. Furthermore, the efficiency of a Metglas/Pb(Z_r,T_i)O₃ gyrator was characterized by varying the values of the resistive load, magnetic bias, and power density. The maximum measured efficiency for the power transferred across an optimal resistor load was greater than 90% under low drive conditions and 89% with a power density of up to 30 W/in.³
