Abstract
Magnetization measurements have been made on polymer bonded melt-spun Nd-Fe-B and on Sm-Co 2:17 powder. Changes in remanence curves with vol ume fraction of magnetic filler are attributed to changes in the magne tic interaction between particles. Measurements on the remanent states indicate that this interaction increases rapidly with volume fraction at low volume fractions, and slowly at high volume fractions. It is s hown that at coercivity, the variation in interaction with the volume fraction is slower than in the remanent state.
