Heterogeneous samples are usually studied using solid-state NMR methods and while the sample is spinning at the magic angle. This is problematic for many cases, where the sample cannot be spun, as in MRI. The alternative methodology of spinning the magnetic field around a static sample has been proposed since the 60's, but not yet successfully applied.

Portable, high-sensitivity low-field detectors are the second axis of our research. Analysis away from the laboratory becomes important, in particular in hostile environments, such as high-radiation areas. It can be also cost effective compared to standard superconducting imaging systems. Imaging and on-line inspection of such industrial processes is a challenging question we try to solve.
