A magnetometer utilizing quantum superconductivity as the basis for the flux sensor element has been designed and used for biochemical susceptibility measurements n the temperature range from 1.5 to 300 K. The sensitivity and reproducibility of this instrument have been tested by measurements on smal lamounts of material of well-known susceptibilities.
