Abstract :
The proton gyromagnetic ratio (gamma´ p) plays a fundamental role in achieving a high accuracy in magnetic measurements. The authors have improved a magnetic field standard using the gamma´ pp-value and related techniques at the KRISS measurement complex for proton gyromagnetic ratio determination. The standard for measuring dc magnetic flux density is intended to cover the range from 20 muT to 2.5 T, with an uncertainty (k = 2) ranging from 4 times 10-6 6 times 10-5 T
