Using the strongest Nd-Fe-B permanent magnet, a miniaturized electron spin resonance apparatus has been developed. lt consists of a Doppler radar Gun-diode used for oscillation and detection of microwave, very precise permanent magnet circuit with Nd-Fe-B magnet. The magnetic circuit enables to change about 15mT without decreasing the high homogeneity. The apparatus was 70 mm(H)x200mm(W)x180mm(D) in size and only 2kg in weight. Its sensitivity was 10^<15> spins/0.1mT. This apparatus is useful for a radical sensor such as geological dating, radiation dosimetry and educational purposes.
