Spintronics

Spintronics is the use of a fundamental property of particles known as spin for information processing. In many ways, spintronics is analogous to electronics, which instead uses the electrical charge on an electron. Carrying information in both the charge and spin of an electron potentially offers devices with a greater diversity of functionality.

    Spintronic properties of layered materials combining magnetism and strong spin–orbit coupling can be tailored by proper optimization of chemical interactions and structural material symmetries. This Review draws a route to achieving best performing material design for reaching the upper limit of spin–orbit torque efficiency in switching magnetization.

    When skyrmions are travelling along a given path their motion is impaired by the skyrmion Hall effect which causes them to veer towards the edges of their track rather than to continue in a linear direction. To help counteract this issue, the authors investigate skyrmion edge interactions demonstrating that a ferromagnetic Co/Fe rim adjacent to the Pd/Fe bilayer on Ir(111) can prevent skyrmion annihilation at the film edge and also stabilizes zero-field skyrmions.

    Intense research efforts have provided mechanistic insight into the spin and anomalous Hall effects in metallic samples, but the effect of extrinsic defects is not yet understood. Here, a scaling law describing the spin Hall response of PtO films with increasing oxygen levels reveals an analogy with the anomalous Hall effect in the insulating regime.

    Laser pulses can be used not only to investigate the ultrafast dynamics of a magnetic system but also to manipulate their magnetization states with potential applications in information storage. To this end, using time-dependent electronic structure simulations, the authors investigate the underlying physics of the laser-induced ultrafast magnetization dynamics in bulk nickel and predict magnetization reversal with a single pulse.

    Heterostructures comprising of different materials provide the possibility to engineer devices with specific properties based on the individual characteristics and interactions between the different components. Here, the authors report the detection of proximity-induced spin-triplet Cooper pairs in a superconductor/ferromagnet/superconductor Josephson junction made of NbN and GdN respectively.
