Abstract

We report an previous terminductivenext term method detecting a previous termmagnetostrictive resonancenext term signal, which is applied to an ultrasonic previous termmagnetostrictivenext term 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 previous termresonancenext term 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 previous termdetection.next term The detected signal is Fourier transformed and wide band spectrum data are obtained. The previous termresonancenext term spectrum data show strong dependencies on the bias dc field strength and direction as well as the dimension of the sample.
