Abstract: We have developed a new and compact β-nuclear magnetic resonance (NMR) system using beta-radioactive nuclei. By using a Halbach array permanent magnet to create a static magnetic field, and a scintillating fiber as a detector, we succeeded in significantly reducing the size and weight of the entire system. The performance of the new spectrometer was tested and evaluated by observing an NMR spectrum of <superscript>19</superscript>O (T<subscript>1/2</subscript> = 26.9 s, I = 5/2) in TiO<subscript>2</subscript>.
