采用单辊急冷技术制备了宽度为10 mm的Fe 79 B 15.5 Si 3.5 C2非晶合金薄带。样品被制成层间MgO绝缘的类甾体。首先在螺线管中在400°C下进行横向磁性退火。随后，将退火的样品在260°C-320°C的DC纵向磁场中再次退火10分钟。我们在不同温度下退火样品，直到累积暴露超过200分钟。横向磁退火和纵向磁退火的结合称为复合磁退火。这是一种新方法。利用该方法，可以容易地控制剩余磁通密度Br。可以控制损耗Pc和励磁功率Pe以获得适当的比率。
Fe 79 B 15.5 Si 3.5 C 2 amorphous alloy ribbons with width of 10 mm were prepared by a single roller quenching technique. The samples were made as teroids which were insulated by MgO between layers. At first the transverse magnetic annealing was carried out at 400°C in a solenoid. Subsequently the annealed samples were once more annealed in a DC longitudinal magnetic field at 260°C-320°C for 10 minutes. We annealed the samples at different temperatures until the cumulative exposure was over 200 minutes. The combination of the transverse magnetic annealing and the longitudinal magnetic annealing is called composite magnetic annealing. It is a new method. Using the method, the residual magnetic flux density Br can be controlled easily. The loss Pc and the exciting power Pe can be controlled to obtain a proper ratio.
