在过去的几十年中，已经开发了基于自旋的器件，以努力实现更快的存储器，具有低功耗。为了实现当前操作电子设备所需的高工作频率，降噪是至关重要的。我们发现，手性分子单层连接硫醇可以降低铁磁器件中的磁散射噪声。手性单层钝化磁无序和表面杂质。我们将这些结果归因于硫醇钝化的组合，与手性诱导的自旋选择性效应的效果。手性分子使磁畴定向，从而减少磁波动。
In the last decades, spin-based devices have been developed in the effort for achieving faster memories, with low power consumption. To realize high working frequencies, which are required for current operating electronics, noise reduction is critical. We show that chiral molecule monolayer linked with thiols can reduce the magnetic scattering noise in ferromagnetic devices. The chiral monolayer passivates both magnetic disorder and surface impurities. We ascribe these results to the combination of thiol passivation, with the effect of the chiral-induced spin selectivity effect. The chiral molecules orient the magnetic domain reducing magnetic fluctuations.
