Does the author of this page really mean "ferromagnetism," not "ferrimagnetism?" 136.142.109.122 22:06, 19 Jul 2004 (UTC)

No. ferromagnetism is a separate property - Omegatron 13:40, Apr 6, 2005 (UTC)

What is the origin of the prefixes ferro- and ferri-? - Omegatron 13:40, Apr 6, 2005 (UTC)

From Latin ferrum which means iron; ferri- may have something to do with ferrite (though ferrite is ferromagnetic). Icek 21:42, 15 April 2006 (UTC)

[edit] Curie vs. Neel temperature?

Both of my solid-state texbooks (Kittel and Ashcroft/Mermin) call the critical temperature at which a ferrimagnet ceases to have a spontaneous magnetization the "Curie temperature", just as for ferromagnets. The term "Neel" temperature is reserved for antiferromagnets with zero magnetic moment in their ordered phase. —Steven G. Johnson 02:04, 16 December 2005 (UTC)

Indeed, Neel is for antiferromagnetic materials, and Curie for ferro- and ferrimagnets. -A nanotechnology student
Considering ferrimagnets contain two sublattices of opposing magnetisation directions they bear more in similarity with a antiferromagnet as opposed to a ferromagnet and hence the describing it using a Neel temperature (which arises in the treatment of two sublattices) is more appropriate. - A Physics student.
That may be your opinion, but Wikipedia only reports standard usage. —Steven G. Johnson
