摘要: Abstract High- T C SQUID sensors having 0.4 pT/√Hz at 1 Hz noise liquid nitrogen temperature are already superior to fluxgate (2.5 Hz, 50 pT p-p). Ac-flipped permalloy magnetoresistors have offset of 10 NT and 15 nT p-p noise. The properties semiconductor, induction other types magnetic field discussed.
