摘要：

We demonstrate electron spin polarization detection and electron paramagnetic resonance (EPR) spectroscopy using a direct current superconducting quantum interference device (dc-SQUID) magnetometer. Our target electron spin ensemble is directly bonded to the dc-SQUID magnetometer that detects electron spin polarization induced by an external magnetic field or EPR in a micrometer-sized area. The minimum distinguishable number of polarized spins and sensing volume of the electron spin polarization detection and the EPR spectroscopy are estimated to be similar to 10(6) and similar to 10(-10) cm(3) (similar to 0.1 pl), respectively.
