-{{page>insert/todo}}+Only three elements are [[ferromagnetic]] at room temperature: [[iron]] Fe, [[cobalt]] Co, and [[nickel]] Ni. Further six are ferromagnetic at lower and very temperatures: [[gadolinium]] Gd, [[terbium]] Tb, [[dysprosium]] Dy, [[holmium]] Ho, [[erbium]] Er, and [[thulium]] Tm. 
 +The rest exhibit either [[diamagnetic]] or [[paramagnetic]] properties. [[Antiferromagnets]] such as [[chromium]] Cr are macroscopically indistinguishable from paramagnets. 
-===== Chemical elements ===== +Magnetic properties of alloys and chemical compounds strongly depends on the electronic and crystallographic configuration of a given materialBoth metallic alloys and oxides are widely used for such engineering materials as [[electrical steels]] or [[soft ferrites]] as well as [[permanent magnets]].

-The rest exhibit either diamagnetic or paramagnetic properties (antiferromagnets are macroscopically indistinguishable from paramagnets). +It is also possible to obtain ferromagnetic behaviour in compound materials which are not made from ferromagnetic elements. This is the case for example for some Heusler alloys.[(Alabama>[[|What are Heusler alloys?
