Zusammenfassung:	A device that utilises an electronic Zeeman splitting effect comprises a solid-state material that comprises at least one spin defect. The device also comprises a magnetic field generator configured to generate a bias magnetic field, and a compensation system to compensate for an effect of changes in temperature on the bias magnetic field. The compensation comprises a temperature sensor configured to measure any of a temperature and a change in temperature of the magnetic-field generator, and a computer device configured to determine a change in the bias magnetic field as a result of a change in the measured temperature or the measured change in temperature. The computer device is further configured to adjust a predetermined bias magnetic field value using the determined change in bias magnetic field and using the value as an input to the compensation system to compensate for the effect of changes in temperature on the bias magnetic field.
