Resumo
A high-performance technique is suggested for generating ultrasonic waves by the magnetic–acoustic method without using a bias field. The technique is based on the frequency doubling of emitted ultrasonic wave as compared to the frequency of the field coil of electromagnetic transducer due to the evenness of magnetostriction. The efficiency of excitation and reception of ultrasonic waves at the doubled frequency without a bias field is compared with that at the base frequency with a bias field.
