【摘要】 利用测定磁化功之差法,研究了旋转磁场退火（RFA）温度T_RFA、保温时间t_RFA和冷速V_RFA对非晶Fe₅Co₇₃Si₁₀B₁₂合金磁各向异性K_Q的影响规律,发现在T_RFA=400℃,t_RFA=30min和V_RFA=6℃/min条件下,RFA可使K_Q降低约80%.K_Q减少的原因是由于RFA驱散了应力-磁致伸缩耦合与原子对方向有序引起的磁各向异性的结果.更多还原

【Abstract】 The modification of the magnetic anisotropy of the amorphous alloyFe₅Co₍73_Si₁₀B₁₂influenced by the annealing in rotary magnetic field under differenttemperatures,times and cooling rates has been investigated by means of the mea-surement of the magnetization difference between parallel and perpendicular tothe longitudinal direction of the ribbon specimens.It was obtained that under theconditions of 400℃,30 min and 6℃/min,the anisotropy may be reduced up toabout 80%.The proposal has also been analyzed that the above-mentioned modi-fication of magnetic anisotropy is caused by dispersing the directional orderingof the coupling of stress-magneto-striction and atomic pairs.更多还原
