“…Possible sources for this coupling are the Lorentz force, the magnetization force, and the magnetostriction force [4]. The magnetostriction [5][6][7] phenomena originated from elastic domain wall motion was used for an oscillator first by Pierce [8]. This phenomenon has been used for actuators and sensors by oscillating them and measuring the frequencies of elastic vibrations accurately.…”

We report an inductive method detecting a magnetostrictive resonance signal, which is applied to an ultrasonic magnetostrictive transducer sample. Slab shaped ferrite samples are mounted in a rf coil and actuated by a pulsed rf magnetic field. A dc magnetic field is also applied and the resonance signal from the sample is detected by the same coil after the rf field is turned off. The detector system is identical to a conventional pulse NMR system with quadrature detection. The detected signal is Fourier transformed and wide band spectrum data are obtained. The resonance spectrum data show strong dependencies on the bias dc field strength and direction as well as the dimension of the sample.
