The dynamic magnetomechanical properties of Sm0.88Dy0.12Fe1.93/epoxy composites with 51 vol% Sm0.88Dy0.12Fe1.93particles were investigated. The dynamic relative permeability (μr33) showed a flat response with frequency for all bias fields (HBias) apart from the fundamental-shape-resonance-induced variations in the vicinity of 42 kHz. The free ( μr 33T) and clamped ( μr 33S) permeabilities attained their maximum values at HBias= 20 kA / m. The elastic modulus at constant field strength (E3H) and that at constant flux density (E3B) exhibited a steady negative -ΔE effect for HBias{less-than or slanted equal to}240 kA/m. The dynamic strain coefficient (d33) displayed a broad negative maximum around HBias= 180 kA / m.
