1960 Science 7 Oct. 920 (advt.) All lines are 60 milligauss peak-to-peak, and the line width is independent of temperature.

1969 Nucl. Instruments & Methods 76 100/1 High precision with the sensitivity of several milligauss was obtained.

1990 Sci. Amer. Apr. 48/3 Their intensity could be as high as one milligauss, about 1/1,000 of the strength of the earth's magnetic field at the surface.
