These systems could be considered as isolated hard nano-objects dispersed in soft network of organic ligands. The main attention was paid to the behavior of the particles whose average size was varied in a controllable manner from 3 to 20 nm. It was found that the magnetic hyperfine interaction was relaxed to null to the temperatures well below liquid nitrogen temperature due to the isolation of particles.
