Time-resolved magnetic helicoidal dichroism (MHD) was successfully used to assess the ultra-fast dynamics of magnetization. This first attempt to use an MHD-based technique was demonstrated on a magnetic vortex structure hosted by a permalloy pacman micropillar (diameter~15nm, thickness~80nm). Micromagnetic simulations allowed to link the features identified in the MHD signal to a process of regeneration […]

Superparamagnetic tunnel junctions have emerged as promising stochastic neurons for low-energy cognitive computing. We report, for the first time, nanosecond-scale mean waiting times between magnetization reversals in perpendicularly magnetized tunnel junctions, enabled by a strong entropic contribution to the thermally activated switching dynamics.   Magnetic tunnel junctions (MTJs) consist of a free and a fixed […]

We propose the concept of a core-shell composite structure coupled antiparallel via dipolar interaction, as the storage layer in perpendicular-shape-anisotropy magnetic random access memory (PSA MRAM). Benefits compared with a standard PSA MRAM include a reduced write time and the stray field. CoFeB core with a Co shell (height 8 nm; diameters 14 and 20 […]
