Resistively-coupled stochastic MTJ for energy-based optimum search (January 22nd, 2024)
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 […]
Read moreDeterministic switching in Voltage Controlled Magnetic Anisotropy Magnetic at Cryogenic Temperatures (January 22nd, 2024)
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 […]

Read moreIn plane reorientation induced single laser pulse magnetization reversal (October 27th, 2023)
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 […]
Read moreSpiking neuron based on magnetic tunnel junction with dual free layer (October 27th, 2023)
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. […]
