As the advance of technology, the manufacturing process of materials has moved forward from the scale of micrometer to sub-micrometer and nanometer. Combining nanotechnology and traditional magnetic materials, nanoscale magnetic materials can be created for applications in biomedical examination and therapy as well as data recording to increase the storage space of a computer. The topic of usin...

In the article we intend to present some recent achievements in the chemistry and physics of 3d and f electron mixed valence systems based on the Prussian blue in the field of molecular magnetism. Prussian blue is sometimes considered as the first coordination compound and in the paper we would like to demonstrate how it is possible to obtain completely new results based on the old one compound.
