We combined chemical synthesis, magnetic microscopy and micromagnetic simulations to provide a comprehensive view of the micromagnetics of chemical modulations in cylindrical nanowires. This sets the ground for their use to investigate the specific aspects of domain-wall dynamics and spin waves in a curvilinear system. Curvilinear and three-dimensional magnetism are a fast-developing field, considering […]

  In the context of intensive research on treatments against diabetes – major health threat to millions of people, we report here on an innovative approach based on mechanobiology. Basically, chronic hyperglycemia is regulated by a supply of insulin, if insufficiently secreted. We show here that the mechanical stimulation of pancreatic beta cells, via the […]

  Spin-torque-nanodiodes based on magnetic tunnel junctions are promising candidates for RF energy harvesters and ultra-low power wake-up receivers with performances that are expected to surpass those of semiconductor diodes. Experiments on magnetic tunnel junctions with perpendicular magnetic anisotropy show how the performances can be optimized upon reducing the magnetic layer thickness and the device […]

  We have investigated the use of spintronic devices to enable the implementation of a Binary Ensemble Convolutional Neural Network. A simulation flow has been setup and allowed to evaluate this disruptive combination and very promising results have been obtained in terms of hardware optimization and power reduction. The use of emerging technologies has been […]

  Control over spin transport in antiferromagnetic systems is essential for future spintronic applications with operational speeds extending to ultrafast time scales. A consortium of physicists at SPINTEC, JGU Berlin and Charles University Prague established the essential role of interfaces for spin current injection and spin current-to-charge current conversion, from the gigahertz (GHz) diffusive to […]

Magnetic skyrmions are appealing for use in logic and memory devices combining small size and fast motion. Here, we propose to exploit skyrmion interactions to perform both logic and memory operations at the nanoscale. Our concept opens a path for novel devices which intrinsically merge high-density non-volatile data storage with computing capabilities. a. Schematic representation […]
