Many proposed spin-wave based devices make use of non-linear behaviour of spin-waves. Here, Dreyer et al show the emergence of non-linear spin waves oscillating at half-integer harmonics in the strong modulation regime. By applying super-Nyquist samp

Abstract Antiferromagnetic (AFM) materials offer an exciting platform for ultrafast information handling with low cross-talks and compatibility with existing technology. Particularly interesting for low-energy cost computing is the spin wave-based re

Abstract Topologically distinct magnetic structures like skyrmions, domain walls, and the uniformly magnetized state have multiple applications in logic devices, sensors, and as bits of information. One of the most promising concepts for applying the

The magnonic currents promise the opportunity for the energy efficient information processing and communication technologies. Here the authors theoretically show the propagating spin waves that carry orbital angular momentum can be electrically tunab

The ferromagnetic oxides La0.7Sr0.3MnO3 (LSMO) and SrRuO3 (SRO) couple antiferromagnetically, leading to a canted spin-structure at the interface’s proximity. Performing first-principles calculations in combination with Monte Carlo and finite tempe

Recently proposed spintronic devices use magnetic skyrmions as bits of information. The reliable detection of those chiral magnetic objects is an indispensable requirement. Yet, the high mobility of magnetic skyrmions leads to their stochastic motion
