Fast Field-Cycling (FFC) NMR is a technique that provides information about the molecular dynamics of a range of materials by using the T1-dispersion curve. After the compensation of the stray magnetic fields coming from external sources, the T1-dispersion curve can extend to magnetic fields in the region of μT allowing for the investigation of slow dynamic processes and determination of the local magnetic fields within the sample. With further development, differences in that region of the curve obtained from biological samples can be associated with the early stages of progress of diseases, leading to a new diagnostic tool.
