Magnetoresistive (MR) sensors have been identified as promising candidates for the development of high-performance magnetometers due to their high sensitivity, low cost, power consumption, and small size. The rapid advance MR sensor technology has opened up a variety applications. These applications are in different areas that require with properties. Future each these requires an overview strategic guide. An roadmap (non-recording applications) was therefore developed made public by...
The lateral motion of a magnetic skyrmion, arising because the skyrmion Hall effect, imposes number restrictions on use this spin state in racetrack memory. A skyrmionium is more promising texture for memory applications, since it has zero total topological charge and propagates strictly along nanotrack. Here, stability skyrmionium, as well dependence its size parameters, such Dzyaloshinskii-Moriya interaction perpendicular anisotropy, are studied by means micromagnetic simulations. We...
Perpendicularly magnetized structures that are switchable using a spin current under field-free conditions can potentially be applied in spin-orbit torque magnetic random-access memory (SOT-MRAM).

Ferrimagnets have the potential to play a key role in spintronics due their high stability, low energy consumption, and rapid magnetic state switching. These characteristics are typically observed ferrimagnetic materials near or angular compensation states. Near point, an external field can disrupt collinearity between sublattices, leading aligned projections. In this work, violation of antiferromagnetic ordering is detected by change direction effective induced spin–orbit torque, without...

Abstract Recently, an ultimate diode effect, a superconducting where electric current shows the state in one direction and normal other direction, has been discovered noncentrosymmetric Nb/V/Ta superlattice. Here, we report that polarity of sign reversal as magnetic field is increased. Such nonlinear behavior effect beyond phenomenology based on Ginzburg–Landau theory. Based recent microscopic study, propose crossover phase transitions finite-momentum pairing states possible origin reversals.
With strong spin-orbit coupling, the largest spin Hall effect among transition metals, tunable interfacial Dzyaloshinskii-Moriya interaction (IDMI), robust perpendicular magnetic anisotropy (PMA), and excellent process compatibility with CMOS devices, tungsten is a key material for spintronic devices. Brillouin light-scattering spectroscopy shows that thickness-dependent phase transformation of W in thin-film multilayers leads to phase-driven oscillations PMA IDMI, due mainly variation...
Abstract To stabilize nontrivial spin textures, e.g., skyrmions or chiral domain walls in ultrathin magnetic films, an additional degree of freedom, such as the interfacial Dzyaloshinskii–Moriya interaction (IDMI), must be induced by strong spin-orbit coupling (SOC) a stacked heavy metal layer. However, advanced approaches to simultaneously control IDMI and perpendicular anisotropy (PMA) are needed for future spin-orbitronic device implementations. Here, we show effect atomic-scale surface...
