Low Field option
Performance:
This option requires the Environmental Magnetic Shield option (available in the MPMS-5S).
Magnet Reset included.
The fluxgate magnetometer (figure) measures the field as a function of position along the axis of the superconducting magnet, providing the magnetic field profile. It nulls the magnetic field at a specific location in the sample chamber following an iterative process. This iterative process can achieve a field smaller than 0.005 Oe.
Once the magnetic field has been nulled, the AC option coils can be used to generate DC high resolution magnetic fields:
