Ferromagnetism

Ferromagnetism Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets...

Ferromagnetism

Historically, the term ferromagnetism was used for any material that could exhibit spontaneous magnetization: a net magnetic moment in the absence of an external magnetic field This general definition is still in common use However, in a landmark paper in 1948, Louis Néel showed there are two levels of magnetic alignment that result in this behavior...
