摘要

利用CoFeSiB/Ru/CoFeSiB组成的合成反铁磁性(SAF)自由层，制备了具有反铁磁性(SAF)自由层的MTJs，因为SAF结构可以减少静磁耦合。通过实验和仿真研究了MTJs的磁开关和隧道磁阻(TMR)比。由于净磁矩较低，SAF结构具有较低的TMR比和矫顽力(H/sub c/)。发现CoFeSiB SAF结构具有较低的交换能。

Magnetization switching and tunneling magnetoresistance effects with synthetic antiferromagnet free layers consisting of amorphous CoFeSiB

MTJs with the synthetic antiferromagnetic (SAF) free layer consisting of CoFeSiB/Ru/CoFeSiB were prepared because a SAF structure can reduce the magnetostatic coupling. Magnetic switching and tunneling magnetoresistance (TMR) ratio of MTJs were investigated by experiment and by simulation. SAF structures show lower TMR ratio and coercivity (H/sub c/) than single free layer due to low net magnetic moment. The CoFeSiB SAF structure was found to have lower exchange energy.
