Talk:Ferrimagnetism

message: Ferro -- pure parallel coupling of spins + coupling energy beyond critical value + particle not too small --> pure ferromagnet in which DOMAINS not spins independently respond to applied fields; spontaneous magnetization at zero applied field; hysteresis, coercive force exist
Super-Paramagnetic -- a would-be ferro, but coupling constant too small (or temperature too high) or particle too small (sub-domain)
Ferri -- two mechanisms, but the the most common are two lattices one with parallel coupling (ferro) and one with antiparallel coupling (antiferro);  magnetite Fe3O4 is a case where Fe3+ ions are in octahedral and tetrahedral sites -- and they couple antiferromagnetically; but Fe2+ ions are in half the octahedral sites too and these Fe2+ couple ferromagnetically; Ferri is just usually weaker form of ferromagnet -- all the same phenomenology though
PLEASE E-MAIL ME and I can send you "all" of magnetism explained in two tables:  (1) the observed phenomenology for each kind of magnetism  and  (2) the microscopic mechanism giving rise to each

message: It would be useful to illustrate how the phenomenon arises and how it is different from ferromagnetism. -- Beland 04:07, 1 April 2007 (UTC)

message: to "Beland":  I wish I knew your e-mail, that way you can see my  "all the kinds of magnetism in two tables".  They are MS-Word tables -- but way too formatted to put into Wikipedia.  The "e-mail" is for anybody who wants me to I will e-mail the two tables.  One gives all the kinds of magnetism in the OBSERVABLE PHENOMENA each kind exhibits; the other table gives the (microscopic) mechanism for how those phenomena come to exist.  e-mail Mark.Weiss@bep.treas.gov and I'll send you the tables.  Last thing:  while I have read Wikipidea I am not expert at modifying its content.  All I know are these discussion pages.  Mostly I want you to see my tables.  How can I get them into Wikipedia -- even as pictures (I can make bitmaps out of my Word tables if absolutely necessary).  The tables are way too formatted, scrunching fonting to fit, etc. for any "plain text" to work.  Anyway, glad you liked (or seemed to like) the content.  I didn't get any "it's crap" comments.  My tables are a synthesis -- in an orderly way! -- of many many books on magnetism.
to anyone else:  if you want two tables that neatly categorize all kinds of magnetism -- ferro- ferri- super-para- para- antiferro- and dia- magnetism, just ask me & I'll e-mail you the two MS-Word tables.  e-mail:  Mark.Weiss@bep.treas.gov —The preceding unsigned comment was added by 199.196.144.11 (talk) 14:47, 23 April 2007 (UTC)
