Unidirectional spin-hall magnetoresistance is a change in the conductivity of ferromagnetic/heavy metal bilayers that is sensitive to the magnetisation of the ferromagnetic layer. This sensitivity makes it a potential candidate for magnetic state readout. Here, Salikhov et al demonstrate ultrafast unidirectional spin hall magnetoresistance driven by terahertz fields

This work presents a comprehensive study of the dynamics of coupled magnetic vortex cores in a multilayer spin valve structure. It is shown that tuning the conservative and non-conservative forces by modulating the applied dc current and magnetic field leads to previously unconsidered complex orbits of the vortex cores and a possible application in reservoir computing is proposed.

Double-sided van der Waals epitaxy across an ultrathin membrane provides a new method for growing a vertical junction with an atomically sharp interface, enabling the direct detection of selection rules for resonant tunnelling between topological surface states.

The particle-like behaviour of magnetic skyrmions is exploited to perform a fundamental neuromorphic computing operation: the weighted summation of synaptic signals. The use of skyrmions enables a compact and energy-efficient implementation that could pave the way for neuromorphic spintronic components that mimic the efficiency of biological systems.

Recent advances in classifying magnets according to spin-group symmetry have expanded the possibilities of unconventional magnetism. Unconventional magnets — such as collinear spin-split antiferromagnets, also known as altermagnets, noncollinear spin-split antiferromagnets and anomalous-Hall antiferromagnets — combine the advantages of ferromagnetism and antiferromagnetism.

Long-distance propagation of a chiral magnonic edge state, through nanochannels and at room temperature, has been observed in engineered manganite thin films that have spiral spin texture and low magnetic damping. The chiral edge state is driven by the dynamic dipolar interaction and is selectively switchable by external fields.

A spintronic diode made from a W/Mn₃Sn bilayer shows broadband rectification at frequencies up to 30 GHz.

A spontaneous Hall effect has been observed in a collinear antiferromagnet at room temperature.
