Context: The last decade has seen the emergence of numerous studies around integrated nanoelectronic technologies for a growing number of application areas, ranging from the Internet of Things, to integrated components specialized in the management and optimization of energy consumption, environmental monitoring, safety and security in the automotive and space industries, support and control in […]

One PhD position and one 12 months postdoc position are available for the following topic. Spintronics concepts and devices, such as magnetic tunnel junctions, offer novel low power hardware approaches for implementing unconventional computing schemes. Some of these make use of the phase dynamics of spintronics oscillators that have the capability to convert a DC […]

We study recurrent networks of binary stochastic Magnetic Tunnel Junctions (sMTJ), aiming at efficiently solving computationally hard optimization problems. After validating a prototyping route, we investigate the impact of hybrid CMOS+MTJ building block variants on the quality of stochastic sampling, a key feature for optimum search in a complex landscape. We carry out a functional […]

Cryoelectronics has the potential to become important in high-performance computing applications and in the context of quantum computing. For low-temperature operation, it becomes imperative to reduce power dissipation, and improved device efficiency could even offset the power consumption required for cooling. In magnetic memories, voltage-controlled magnetic anisotropy (VCMA) is a promising approach to minimize the […]

Spin electronics applies to a wide range of materials: metals, where spin is transported by electrons, but also magnetic insulators, where spin is transported by magnons. The latter are of interest because in certain insulators, such as yttrium iron garnet (YIG), it is predicted that one could reach a state of superfluidity, i.e. spin transport […]

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. […]
