ferromagnetism

FEH-roh-mag-nuh-tih-zum

Definition

A form of magnetism where certain materials, like iron, exhibit strong magnetic properties and remain magnetized even after an external magnetic field is removed.

Etymology

Derived from the Latin 'ferrum' meaning iron, combined with the Greek 'magnes' for magnet and the suffix '-ism' denoting a state or quality.

In the news

In the article, ferromagnetism is used to describe the ability of thin Fe5GeTe2 films to maintain their magnetic state at relatively high temperatures, a key property for potential use in future memory devices.
