Controlling magnetic domain wall motion in nanowires requires a thorough knowledge of the depinning mechanisms. Here, the authors show that current-induced intrinsic depinning has a different energy barrier than magnetic field-induced extrinsic depinning, and succeed in quantifying the respective barriers.

Orbitronics uses the electron’s orbital angular momentum to enable next-generation memory and computing technologies. This Perspective outlines recent advances, key challenges and future directions in this rapidly evolving field.

Realizing stable, room-temperature magnetic skyrmions that can be moved along current is challenging. Here, the authors observe skyrmion bubbles in a synthetic antiferromagnetic coupled multilayer at room temperature and demonstrate its current-induced motion free from the skyrmion Hall effect.

Antiferromagnet/ferromagnet bilayers are shown to exhibit large enough spin–orbit torque to switch the magnetization of the ferromagnetic layer without the application of external magnetic fields.

The control and manipulation of the magnetization of thin metallic films by means of an electric current is a promising strategy for ensuring that potential spintronic applications are energy efficient. It is now shown that large changes in the current-induced magnetic field can arise as a result of varying the thickness of the Ta layer in Ta|CoFeB|MgO heterostructures.

Spin-orbit torque can drive switching in ferromagnets, and therefore can be used for the electrical writing of magnetic bits. Here, Yoon et al. take this essential idea a step further, demonstrating mutual switching, where a ferromagnet can drive switching in an antiferromagnet, switching the sign of the spin-orbit torque itself.

Manipulation of the quantum-metric structure to produce topological phenomena has rarely been studied. Now, flexible control of the quantum-metric structure is demonstrated in a topological chiral antiferromagnet at room temperature.

Designing energy-efficient and scalable hardware capable of accelerating Monte Carlo algorithms is highly desirable for probabilistic computing. Here, Singh et al. combine stochastic magnetic tunnel junction-based probabilistic bits with versatile field programmable gate arrays to achieve this goa

In the non-collinear antiferromagnet Mn₃Sn, a spin–orbit torque makes the collective octupole moment and individual moments rotate in opposite directions, leading to a sign-reversed switching polarity compared with collinear magnets.

There has been much interest in using the probabilistic switching of magnetic tunnel junctions in unconventional computing, but to do so requires a detailed understanding of this switching. Here, Funatsu et al rigorously determine the switching exponents in superparamagnetic tunnel junctions.

Sensitive spin rectifier devices can be used to create rectennas that harvest ambient radiofrequency signals between –62 and –20 dBm, and can be used to create on-chip co-planar-waveguide-based spin rectifier arrays with large zero-bias sensitivity and high efficiency.

Spin torque oscillators (STOs) are attractive potential alternative for many high frequency applications, due to their small area and CMOS compatibility. Here, Sharma et al succeed in the electrical synchronization of four STOs, and use their setup to demonstrate wireless and battery-free energy harvesting using eight STOs.

This allows versatile non-volatile tuning of the mutual synchronization of chains of up to four oscillators and provides a path toward individual oscillator control in large oscillatory arrays.

Spin Hall nano-oscillators can be tuned via magnetic fields and the drive current, but individual oscillator control in large arrays remains a challenge. Here, the authors provide individual control of the threshold current and the auto-oscillation frequency by voltage-controlled magnetic anisotropy.

Microrod patterns were fabricated on PDMS sheets utilizing porous silicon wafers as templates. The prepared microrod PDMS surface showed high water and oil contact angles. To discuss the mechanism, theoretical contact angles were calculated utilizing Wenzel model and Cassie-Baxter model, and compared with the measured values. Furthermore, it was confirmed that the microrod PDMS surface has self-cleaning property.
