Descripción del proyecto
Una novedosa plataforma para el movimiento de los skyrmiones basada en nanodispositivos tridimensionales
Los skyrmiones son estructuras magnéticas estables y móviles con un giro topológico, lo que las hace atractivas para el almacenamiento y procesamiento de datos de baja energía y alta densidad, un reto fundamental en la tecnología moderna. Sin embargo, su movimiento bajo estímulos de corriente y temperatura es complejo y difícil de manipular, y su detección eléctrica es todo un reto. El equipo del proyecto 3D-Sky, financiado por las Acciones Marie Skłodowska-Curie, utilizará la nanofabricación tridimensional para crear una nueva plataforma que permita controlar los efectos térmicos e investigar el panorama energético que rige la dinámica de los skyrmiones.
Objetivo
The overall power consumption of information technology accounts for almost 10% of the global energy demands and it is predicted to reach 20% in 2030. As a result, we need new ways to store and compute data utilizing more efficient and environmentally cleaner alternatives to current technologies, and the EU should be leading this transformation. The development of a low-power non-volatile memory is one of the most sought-after technologies and racetrack memories based on topological magnetic Skyrmions are one of the most promising candidates. There are, however, several drawbacks for spintronic devices based on Skyrmions: their trajectories under currents are nontrivial; the thermal contribution to Skyrmion motion is yet to be well understood, and fully electrical detection of Skyrmions is challenging due to the small contribution of the topology to the Hall effect.
In 3D-Sky, I propose to take advantage of state-of-the-art 3D nanopatterning to obtain fine control over the energy landscape for the motion of Skyrmions in 3D racetracks. For this, I will exploit the precise and unique tuning of thermal and geometrical properties that 3D devices enable to decouple the nanostructure from the substrate opening the possibility to use much higher temperature gradients to tackle the main drawbacks of Skyrmion racetrack memories. In short, in 3D-Sky I aim to create a platform for Skyrmion motion based on 3D nanodevices focusing on the impact of temperature on their dynamics, nucleation and properties. This will provide the fundamental knowledge needed to understand thermal-driven Skyrmion motion in different systems including the different driving forces in play. Furthermore, I will tackle the current challenges in reliable nucleation and electrical detection of Skyrmions taking advantage of the singular properties of 3D nanostructures for the creation of defects and efficient heating.
