Our laboratory has demonstrated rat magnetocardiography using NV centers in diamond. Currently, we are targeting magnetoencephalography, but since the intensity of magnetoencephalography is weak to detect, it is essential to further improve the sensitivity of the sensor. The Ramsey method is one of the promising methods for further improvement of sensitivity. In this study, we developed a sensor head with high-sensitivity using the Ramsey method for magnetoencephalography.
