By using THz spintronic emission, we could study the spin-charge conversion mechanisms in 2D materials. High crystalline quality 2D materials are grown by molecular beam epitaxy on large area and CoFeB is deposited on top using soft UHV sputtering to obtain sharp interfaces. Such model system allows us to identify and quantify the spin-charge conversion […]

The setting of spin textures in antiferromagnets (AFMs) provides a potential route to antiferromagnetic spintronic devices with non-collinear spin states such as skyrmions, bubbles and domain walls. In this work, a consortium of physicists from SPINTEC and York establish a solution for overcoming the challenge of nucleating localized real-space spin textures in AFMs, promoting the […]

We demonstrate that single pulse all optical helicity independent switching can be generalized for a large range of rare earth–transition metal multilayers. The threshold fluence for switching is observed to be independent of the pulse duration and, at high laser intensities, concentric ring domain structures are induced, unveiling multiple fluence thresholds. These striking switching features […]

We demonstrate that a perpendicular magnetic tunnel junction (MTJ) is capable of emulating an artificial spiked neuron. The magnetic stack has been designed so that the MTJ has two free layers, whose magnetization can be driven in a windmill-like dynamic by the spin transfer torque. The output-spiking rate is tunable by the dc bias voltage. […]
