Chromium is in elemental form, it displays paramagnetic properties. Recently, it has been discovered that chromium can display different magnetic properties depending on its heating and cooling, which affects the electrons' spinning alignments. Compounds of chromium, such as chromium dioxide, are considered to be ferromagnetic. The ferromagnetic properties of these compounds allow them to be used in data tape, a way to store information. Chromium can be added to other compounds while maintaining its magnetic properties, and this depends on the quantity of other elements in the compound. For example, some stainless steel compounds are magnetic depending on the amount of chromium they contain.
