Abstract :
The proton gyromagnetic ratio (γ´p) plays a fundamental role in achieving high accuracy in magnetic measurements. We have improved our magnetic flux density standards using the γ´p-value and related techniques developed at Korea Research Institute of Standards and Science (KRISS). The standards are used for the calibration of magnetometers and support the test of sensors and materials in the range from 20 μT to 2.5 T with (4 to 80) μT/T uncertainties (k=2).
