Abstract

A theoretical model of a spin-tunnel element containing a synthetic antiferromagnet is developed, based on the concept of the coherent rotation of magnetization vectors of ferromagnetic nanolayers under the influence of an external magnetic field. The obtained field dependences \(\cos ({{\theta }_{r}}(h))\) for nearly compensated and non-compensated synthetic antiferromagnets show that a 30% non-compensated synthetic antiferromagnet switches magnetization at lower fields.

自旋隧道元件中合成反铁磁体磁性层的磁化反转特征

基于铁磁纳米层在外加磁场作用下磁化矢量相干旋转的概念，建立了含合成反铁磁体的自旋隧道元件的理论模型。得到的近补偿和非补偿合成反铁磁体的场依赖性\(\cos ({{\theta }_{r}}(h))\)表明% non-compensated synthetic antiferromagnet switches magnetization at lower fields.
