===Electrically induced ferromagnetism===
Recent research has shown evidence that ferromagnetism can be induced in some materials by an [[electric current]] or voltage. Antiferromagnetic LaMnO<sub>3</sub> and SrCoO have been switched to be ferromagnetic by a current. In July 2020, scientists reported inducing ferromagnetism in the abundant [[diamagnetic]] material [[iron pyrite]] ("fool's gold") by an applied voltage.<ref name="Phys">{{cite news |title='Fool's gold' may be valuable after all |url=https://phys.org/news/2020-07-gold-valuable.html |access-date=17 August 2020 |work=phys.org |language=en}}</ref><ref name="Voigt">{{cite journal |last1=Walter |first1=Jeff |last2=Voigt |first2=Bryan |last3=Day-Roberts |first3=Ezra |last4=Heltemes |first4=Kei |last5=Fernandes |first5=Rafael M. |last6=Birol |first6=Turan |last7=Leighton |first7=Chris |title=Voltage-induced ferromagnetism in a diamagnet |journal=Science Advances |date=1 July 2020 |volume=6 |issue=31 |pages=eabb7721 |doi=10.1126/sciadv.abb7721 |pmid=32832693 |pmc=7439324 |bibcode= 2020SciA....6.7721W|language=en |issn=2375-2548 |doi-access=free }}</ref> In these experiments, the ferromagnetism was limited to a thin surface layer.
