Skyrmions are objects with whirled magnetization protected by their topology that can be created by different means, however, without control of their position. Here, the authors present a method exploiting x-rays to create skyrmions at the beam position allowing for creation of artificial skyrmion lattices.

Whilst neutron scattering is a powerful tool for studying spin fluctuations in materials, its availability is limited to large-scale user facilities. Here, the authors demonstrate how the pumping of pure spin currents can be used as a desktop probe to detect an antiferromagnetic transition.

The topological Hall effect is observed at above room temperature in a bilayer heterostructure composed of thulium iron garnet and platinum, suggesting the formation of skyrmions in a magnetic insulator through the interfacial Dzyaloshinskii–Moriya interaction.

Non-adiabatic spin-transfer torque in antiferromagnetically coupled ferrimagnets acts like a staggered magnetic field and can induce efficient domain wall motion.

The spin-orbit torque (SOT) induced magnetic switching makes metal/magnetic insulators bilayers preferred in the energy efficient spintronic applications. Here the authors show SOT switching in W/TmIG bilayers and reveal the dimension crossover of SOT as a function of TmIG thickness.

The temperature-dependent transverse elongation of ferrimagnetic bubbles provides experimental evidence for an evanescent skyrmion Hall effect at zero spin density.

Heterostructures consisting of ferromagnets and heavy metals have become a focus of interest because their strong spin–orbit coupling allows for efficient current-induced magnetization switching phenomena. Now, a magnetically doped topological insulator bilayer is shown to display a range of appealing characteristics for current-induced magnetization switching, including a significantly enhanced efficiency.

The spin Seebeck effect has hitherto relied on a temperature gradient in a magnetic system to generate an electric current based on the intrinsic spin of electrons. It has now been demonstrated in a non-magnetic material. See Letter p.210

Magnetic excitations in a ferromagnet known as magnons can be converted into charge currents through a relativistic interaction that couples the spin of an electron with its orbital angular momentum.

Fast field-driven antiferromagnetic spin dynamics is realized in ferrimagnetic Gd₂₃Fe_67.4Co_9.6 thin films at the angular momentum compensation point. In particular, at this point, the field-driven domain wall mobility is found to be enhanced.

A major advantage of antiferromagnets for applications is the lack of stray fields and insensitivity to magneto-electric perturbations, however, this also makes electric control of AFMs challenging. Here, focusing on a non-collinear AFM, Mn₃Ge/Sn, Wu et al demonstrate fast domain wall motion, with remarkably low current density, and extend our understanding of spin-transfer torques that drive this to noncollinear antiferromagnetic systems.

A theoretical study proposes the use of molecular magnets in a type of transistor in which the flow of collective spin excitations transports and processes information.

Spin–orbit torques in a geometrically asymmetric device made from a perpendicularly magnetized ferromagnet can switch its magnetization without the assistance of an applied magnetic field.

Electric field control of spin–orbit torque and magnetization switching can be achieved in a Cr-doped topological insulator thin film incorporated in a field-effect transistor structure, promising gate-controlled spintronic applications.

Topological magnetic monopoles are non-local spin textures that are robust to thermal and quantum fluctuations, but they are difficult to study at the nanoscale in real space. Now, soft X-ray vector ptycho-tomography is demonstrated to determine the three-dimensional magnetization vector and emergent magnetic field of such magnetic monopoles in a ferromagnetic meta-lattice.
