High-sensitive detection of small spin ensemble in pulsed high magnetic fields by introduction of micromachine technology

使用脉冲磁体可以获得强磁场，但是由于其有限的脉冲持续时间，难以实现高灵敏度。在本研究中，我们注意到微机械技术，并开发了一个测量系统，具有高灵敏度和快速响应使用微器件。利用这种技术，我们成功地在太赫兹区域的电子自旋共振的机械检测。此外，还制造了定制的杠杆，以优化强磁场中的测量设备。

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.
