“…It implies that the effects of magnetic annealing on the magnetostrictive performance show a strong dependence on the magnetocrystalline anisotropy of the material. Recently, we found that the magnetostriction under free conditions of a /1 1 0S oriented Tb 0.36 Dy 0.64 (Fe 0.85 Co 0.15 ) 2 alloy (magnetocrystalline anisotropy constant K 1 is approximately 2.14 Â 10 6 erg/cm 3 [14], a little larger than 1.67 Â 10 6 erg/cm 3 for Tb 0.3 Dy 0.7 Fe 1.95 [15]) can be dramatically improved after magnetic annealing in a relatively lower field of 240 kA/m [16]. However, no obvious magnetostriction ''jump'' effect can be observed under a uniaxial compressive pre-stress [17].…”
