A Standard Quantum Measuring System for Reproduction and Measurement of Low Direct Magnetic Field in the Range 0.1 μT-1.5 mT

A wide-range low permanent field standard measurement system is described, intended for use within the geomagnetic range of natural magnetic fields on the Earth's surface (EMF) (20 μT - 100 μT), fields of near and distant outer space (0.1 μT - 20 μT), and precision current-carrying high-uniform-field coil systems used in fundamental and applied research (up to 1.5 mT)
