通过电流测量探测自旋反转和章动

Detection of spin reversal and nutations through current measurements

J. Fransson

摘要:

嵌入在铁磁接触之间的隧道结中的单个自旋的动力学强烈地受到与隧穿电子的交换耦合的影响。跨结的偏置电压引起的局部自旋反转的力矩示出有一个可测量的隧道电流的影响。此外,谐波偏置电压的频率被局部自旋动力学拾取,并被传递回产生倍频分量的电流。

英文摘要:

The dynamics of a single spin embedded in a the tunnel junction between ferromagnetic contacts is strongly affected by the exchange coupling to the tunneling electrons. Moment reversal of the local spin induced by the bias voltage across the junction is shown to have a measurable effect on the tunneling current. Furthermore, the frequency of a harmonic bias voltage is picked up by the local spin dynamics and transferred back to the current generating a double frequency component.
