Hi, You should look in any standard magnetics text book for this under the "Weiss Equation". The best picture I know is Figure 14-7 in Bozorth "Ferromagnetism",orgininally published by Bell Labs and Van Nostrand in 1951! It should be available in any good technical library. You can also look in Google under "Weiss Equation" Basically, as the Curie point is approached the magnetude of the applied field becomes more important.
