In article number 1804557, Danny Porath, Yossi Paltiel, and co‐workers demonstrate imprinting of ferromagnetism on super paramagnetic iron oxide nanoparticles (SPIONs) following asymmetric self‐assembled adsorption of polyalanine chiral molecules. The adsorbed chiral molecules stabilize the magnetization direction of SPIONs at room temperature with a coercive field of about 80 Oe. This procedure allows...
The rapid growth in demand for data and the emerging applications of Big Data require the increase of memory capacity. Magnetic memory devices are among the leading technologies for meeting this demand; however, they rely on the use of ferromagnets that creates size reduction limitations and poses complex materials requirements. Usually magnetic memory sizes are limited to 30–50 nm. Reducing the size...
A novel Hall circuit design that can be incorporated into a working electrode, which is used to probe spin‐selective charge transfer and charge displacement processes, is reviewed herein. The general design of a Hall circuit based on a semiconductor heterostructure, which forms a shallow 2D electron gas and is used as an electrode, is described. Three different types of spin‐selective processes have...
