Dynamic magnetic and magnetoelastic properties of epoxy-TbFe2 composites

The static and dynamic magnetic and magnetoelastic properties of epoxy-bonded TbFe2 were investigated as functions of bias field. frequency and AC drive field, The peak in d(33) vs. bias field was shifted to higher bias field. A small negative DeltaE effect was observed in field <80 kA/m. Both d(33) and k(33) were Much lower, compared with bulk Terfenol-D or its composites. (C) 2002 Elsevier Science B.V.
