Electrochemical process changes magnetism in ferromagnets reversibly

Magnets are well-known from the physics lessons at school, but they are hardly covered in chemistry lectures; and it is still a chemical process by means of which researchers at Karlsruhe Institute of Technology (KIT) have succeeded in controlling magnetic properties in bulk ferromagnets. While physical processes may influence the orientation of the magnetic fields, the chemical process in this case controls magnetism in carefully chosen strongly ferromagnetic material systems. The working principle used in this case is similar to the concept of lithium-ion batteries.
