| Research Abstract |
Strong magnetic field can be obtained using a pulse magnet, but it is difficult to achieve high sensitivity due to its limited pulse duration. In this study, we have paid attention to micromachine technology, and have developed a measurement system with high sensitivity and fast response using microdevices. With this technique, we succeeded in mechanical detection of electron spin resonance in the terahertz region. Besides, custom cantilevers were fabricated to optimize measurement devices in strong magnetic fields.
