Utilizing the Chiral Induced Spin Selective Effect (CISS) to Realize Simple Spintronics Devices

With the increasing demand for miniaturization, nano-structures are likely to become the primary components of future integrated circuits. Different approaches are being pursued towards achieving efficient electronics, among which are spin electronics devices (spintronics). In principle, the application of spintronics should result in reducing the power consumption of electronic devices.

A new, promising, effective approach for spintronics has emerged using spin selectivity in electron transport through chiral molecules, termed Chiral-Induced Spin Selectivity (CISS). Recently, by utilizing this effect we demonstrated a magnet-less magnetic memory. Also we achieve local spin-based magnetization generated optically at ambient temperatures. The locality is realized by selective adsorption of the organic molecules and nano particles. Lastly we have been able to show chiral proximity induced magnetization on the surface of ferromagnetic and superconducting materials. The magnetization is generated without driving current or optically exciting the system. Interestingly, the opposite effect supplies a simple new quantum spin interaction which enables enantio-selection. The interaction of chiral molecules with a perpendicularly magnetized magnetic substrate is enantio-specific. In the talk I will give a short introduction about spintronics and the CISS effect. Then I will present ways to achieve simple spintronics devices utilizing the effect.
