Abstract

Nanocrystalline DyFe₂ melt-spun ribbons with good low field magnetostrictive properties are bonded with a phenol-type binder to form bulk composites. The optimum binder content estimated by considering both magnetostrictive and mechanical properties is about 6 wt. %. A magnetostriction of 202 ppm (at 1.1 kOe), together with a d^max₃₃ value of 0.68 ppm/Oe is achieved in this work.
