Ensemble-averaged Rabi oscillations in a ferromagnetic CoFeB film

External driving of Rabi oscillations is a first step in the coherent manipulation of spin systems. Here the authors use ultrafast optical pulses to produce classical Rabi oscillations in ferromagnetic CoFeB, enabling the exploration of coherent phenomena in dense ferromagnetic ensembles.

Topological repulsion between domain walls in magnetic nanowires leading to the formation of bound states

The manipulation of domain walls in magnetic nanodevices is a topic of increasing technological relevance. This study examines the interactions that occur between vortex domain walls in permalloy nanowires, and finds that bound states occur between domain walls with opposite magnetic charge.

Enhanced stochasticity of domain wall motion in magnetic racetracks due to dynamic pinning

Understanding the details of domain wall motion in nanowires is important for magnetic racetrack memories. Jiang and co-workers show that this motion can become more random by varying the magnetic field, pinning the domains at several local imperfections of the nanowire.

Domain wall trajectory determined by its fractional topological edge defects

When a domain wall of a given chirality is injected into a magnetic nanowire, its trajectory through a branched network of Y-shaped nanowire junctions—such as a honeycomb lattice, for instance—can be pre-determined. This property has implications for data storage and processing.

Ferrimagnetic Heusler tunnel junctions with fast spin-transfer torque switching enabled by low magnetization

Owing to its very low magnetization, small currents suffice to write a ferrimagnetic Heusler memory layer in complementary metal–oxide–semiconductor-compatible magnetic tunnel via spin-transfer torque, which can help in shrinking the memory cell and extending the application space for magnetic random-access memory.

Probing vortex-core dynamics using current-induced resonant excitation of a trapped domain wall

A magnetic vortex trapped by a notch in a nanowire is no larger than 10 nm, but both the direction and polarity of the vortex can now be measured without applying a magnetic field. In this set-up, the vortex is therefore both stable and switchable for use in possible device applications.

Oscillatory dependence of current-driven magnetic domain wall motion on current pulse length

Experiments show that domain walls in ferromagnetic wires can be moved on very short timescales, by applying nanosecond-long pulses, and also detail a so-called 'boomerang' effect, where the domain walls are driven out of their confining potential, in the opposite direction of the current pulse.

Enabling complex nanoscale pattern customization using directed self-assembly

Block copolymers are frequently used as self-assembling materials for nanoscale patterns, but controlling assembly for complex patterning is challenging. Here, the authors integrate masking features into organic–inorganic guide patterns, enabling precise pattern customization by directed self-assembly.
