Scientists discover magnetic ‘persuasion’ in neighboring metals

Certain materials can be swayed by their neighbors to become magnetic, according to a new study. The researchers found that as electrons flowed out of the manganite into the neighboring nickelate, the non-magnetic nickelate suddenly became magnetic — but not in a typical way.
