概要
In this study, superconducting electromagnetic acoustic transducer (EMAT) is developed to transmit strong ultrasound, which is expected as an experimental tool for mechanism study of nonlinear ultrasound. For the purpose, EMAT experiment is carried out using uniform and strong filed generated by a superconducting magnet, and surface displacement of specimen is measured by a laser Doppler vibrometer. As the result, the linear relationship between the surface displacement and magnetic flux density was confirmed.
