补充资料:磁记忆材料
      具有两种或两种以上容易识别的稳定磁状态的磁性材料。一般是有矩形磁滞回线的矩磁材料。用于制造磁存储(记忆)元件的磁心、磁棒、磁膜。
  
  记忆磁心应具有以下磁特性:①较大的剩磁比R(R=Br/Bm)。R 越大,磁滞回线的矩形度越好。②较大的矩形比Rs(Rs=B(-1/2Hm)/Bm,式中B(-1/2Hm)为最大磁场强度Hm一半时的磁通密度)。Rs愈大,磁滞回线的拐角愈接近直角,磁滞回线的斜率越陡,磁心的抗干扰能力也越强。一般Rs为0.75~0.90。③较小的矫顽力(Hc<0.8千安/米)。因磁心通入的脉冲电流只有几百毫安,如Hc太大,磁心的磁化方向翻转就发生困难。④较小的温度系数,使具有较高的温度稳定性。⑤较高的居里温度和较小的损耗。
  
  金属矩磁材料是某些经过处理的铁镍合金,其优点是饱和磁通密度高,初始磁导率大;但电阻率小,涡流损耗大,工作频率低,速度慢,轧成薄带后可用于较高频率。铁氧体矩磁材料又分为常温和宽温矩磁材料两种。前者居里温度低,宜在常温下工作,如镁锰铁氧体;后者居里温度高,能在较宽温度范围工作,如锂锰铁氧体。
