In order to obtain data with excellent reproducibility, a stable and linear magnetic field is necessary. To obtain a stabilized static magnetic field, the JES-X330 employs a Hall element with good linearity, and the entire Hall element is thermally controlled to guarantee a magnetic field stability as high as 5 x 10-6 / 0C・h. The high stability shown is 100 times superimposed ESR spectra of perylene cation radical with ±0.1 mT magnetic field sweep in one hour measurement.
