Abstract:
The construction and characterization of static magnetic density flux and gradient standards by using permanent magnets is presented. In the first homogeneity is high enough to be measured by a nuclear magnetic resonance magnetometer, confirming the traceability of the standard. In the second case a gradient standard is shown, which is useful to study the magnetic properties of materials applicable to nanotechnology. The experimental results obtained by Hall probes are in agreement with theoretical calculation. Designing consideration about materials choice and mounting are also addressed.
