Chaotic dynamics in a macrospin spin-torque nano-oscillator with delayed feedback
Jérôme Williame, Artur Difini Accioly, Damien Rontani +2
A theoretical study of delayed feedback in spin-torque nano-oscillators is presented. A macrospin geometry is considered, where self-sustained oscillations are made possible by spi…
Material developments and domain wall based nanosecond-scale switching process in perpendicularly magnetized STT-MRAM cells
Thibaut Devolder, Joo-Von Kim, J. Swerts +6
We investigate the Gilbert damping and the magnetization switching of perpendicularly magnetized FeCoB-based free layers embedded in tunnel junctions adequate for spin-torque opera…
Current-driven skyrmion expulsion from magnetic nanostrips
Myoung-Woo Yoo, Vincent Cros, Joo-Von Kim
We study the current-driven skyrmion expulsion from magnetic nanostrips using micromagnetic simulations and analytic calculations. We explore the threshold current density for the…
Current-driven skyrmion dynamics in disordered films
Joo-Von Kim, Myoung-Woo Yoo
A theoretical study of the current-driven dynamics of magnetic skyrmions in disordered perpendicularly-magnetized ultrathin films is presented. The disorder is simulated as a granu…
Skyrmion Gas Manipulation for Probabilistic Computing
Daniele Pinna, Flavio Abreu Araujo, Joo-Von Kim +5
The topologically protected magnetic spin configurations known as skyrmions offer promising applications due to their stability, mobility and localization. In this work, we emphasi…
