Keywords: spintronics, antiferromagnet, growth and characterization (Some figures may appear in colour only in the online journal) Chiral Spintronics is an emerging field that studies the structural (static) and dynamical chirality in spintronics. For the dynamical chirality here, in the literature different terms are used to A current drawback of spintronics is the large power that is usually required for magnetic writing, in contrast with nanoelectronics, which relies on “zero-current,” gate-controlled operations. Efforts have been made to control the spin-relaxation rate, the Curie temperature, or the magnetic anisotropy with a gate voltage, but these effects are usually small and volatile. We used Spintronics has received a great attention and considerable interest within the past decades.

Spintronics is a promising technology which aims to solve the major problems existing in today’s conventional electronic devices. Realistically, this technology has the ability to combine the main functions of the modern semiconductor microelectronics and magnetic storage devices in single chip. Spintronics use magnetic materials patterned at the nano-scale to produce spin polatized currents which drive a new class of beyond CMOS components which include magnetic field sensors, non-volatile memories and RF devices. Spintronics research team (picture from April 2018) Abstract In this paper, we review our recent experimental developments on antiferromagnet (AFM) spintronics mainly comprising Mn-based noncollinear AFM metals. IrMn-based tunnel junctions and Hall devices have been investigated to explore the manipulation of AFM moments by magnetic fields, ferromagnetic materials and electric fields.

In 2008, Otani and colleagues reported an experiment where a charge current that runs through a magnet to a ground caused a magnetization reversal of another magnet that was situated outside of the current path, yet its magnetization reversed due to the non-equilibrium spin-accumulation under it. A spin current is generated by spin pumping at the FM –NM interface (grey arrows). The time- dependent spin polarization of this current (indicated as purple arrow) rotates almost entirely in the y –z plane. The small time-averaged d.c.

Why might THz spintronics be interesting for computing? The current semiconductor transistor developments with 12 nm gate-pitch face serious leakage currents and power consumption is increasing. To a certain extent, on-chip power management allows power consumption to be balanced, especially for mobile devices. 46 46. Editorial, Nat. Nanotechnol.
