Extract

The magnetic anisotropy of crystals of calcite and sodium nitrate does not alter between room temperature and liquid nitrogen temperature. By using such diamagnetic crystals, it is easy to compare strong magnetic fields to 1 part in 1000. The effect is large enough for the measurement of fields of the order of 100 gauss, but in small fields the accuracy is limited by ferromagnetic contamination.
