Abstract
             A new concept in which spin current is produced by using the spin selectivity in electron transport through chiral layers termed the Chiral-Induced Spin Selectivity (CISS) effect will be presented [1]. Recently, by utilizing this effect we demonstrated a simple magnetless spin based magnetic memory [2,3]. When chiral molecules are adsorbed on the surface of thin ferromagnetic film, they induce magnetization perpendicular to the surface, [4] on s wave superconductor a triplet is generated [5]. CISS effect based devices were scaled down to the 30nm size replacing the continuous ferromagnetic layer with magnetic nano platelets [6,7]. ALD Chiral oxides can supply 99% spin polarization [8]. The CISS-based spintronics technology has the potential to overcome the limitations of other magnetic-based memory technologies and to facilitate the fabrication of inexpensive, high-density memory and other spintronics elements.                                                                                                                             (1) Nature Review Chemistry 3, 250–260 (2019).(2) Nature Communications 4, 2256 (2013). (3) Nature Review Physics 3, 328–343 (2021).(4) Nature Communications, 8 14567 (2017).(5)  Nano Letters 19 8, 5167-5175 (2019).(6) Adv.
