Characteristic investigation we use vsm and mts to study the main result as follows : ( 1 ) the hysteresis loop of co / al2o3 / feni mtj is a typical two hc loop 3 ）结构特性研究在样品性质研究方面的主要结果： （ l ） co ai八feni隧道结磁滞回线是一典型的隧道结双比曲线。 （ ） co ai 。
2.
Study on the fabricating method the fe / al2o3 / fe mtj and co / al2o3 / feni mtj are prepared by ion - beam sputtering systems . the fexcu ( 1 - x ) granule films were evaporated directly using a high vacuum electron beam evaporation . some samples of granule films are annealed at 340c 用高真空镀膜机制备了fe _ xcu _ ( ( 1 - x ) )系列颗粒膜，并对部分膜做了加热退火处理，样品被加热到340并且保温2小时。
