Magnetic storage based on racetrack memory is very promising for the design of ultra-dense, low-cost and low-power storage technology. Information can be coded in a magnetic region between two domain… Expand
Cortical and subcortical connections of the human claustrum revealed in vivo by constrained spherical deconvolution tractography.
The claustrum is a thin layer of gray matter that is at the center of an active scientific debate. Recently, Constrained Spherical Deconvolution (CSD) tractography has proved to be an extraordinary… Expand
Ultralow-current-density and bias-field-free spin-transfer nano-oscillator
We report microwave measurements on STNOs built with MgO-based magnetic tunnel junctions having a planar polarizer and a perpendicular free layer, where microwave emission with large output power, excited at ultralow current densities and in the absence of any bias magnetic fields is observed.

A framework for the damage evaluation of acoustic emission signals through Hilbert-Huang transform
Abstract The acoustic emission (AE) is a powerful and potential nondestructive testing method for structural monitoring in civil engineering. Here, we show how systematic investigation of crack… Expand
Magnetic skyrmions: from fundamental to applications
High-power coherent microwave emission from magnetic tunnel junction nano-oscillators with perpendicular anisotropy.
The excitation of the steady-state precessions of magnetization opens a new way for nanoscale microwave oscillators by exploiting the transfer of spin angular momentum from a spin-polarized current… Expand
Magnetization switching driven by spin-transfer-torque in high-TMR magnetic tunnel junctions
This paper presents a numerical study of magnetization switching driven by spin-polarized current in high-TMR magnetic tunnel junctions (TMR>100%). The current density distribution throughout the… Expand
Basal ganglia network by constrained spherical deconvolution: A possible cortico‐pallidal pathway?

- 11 August 2017
The aim of this paper is to introduce a compact model for perpendicular spin-transfer torque (STT)-magnetic tunnel junctions (MTJs) implemented in Verilog-A to assure easy integration with electrical… Expand
Strong linewidth variation for spin-torque nano-oscillators as a function of in-plane magnetic field angle
We measure the microwave signals produced by spin-torque-driven magnetization dynamics excited by direct currents in patterned magnetic multilayer devices at room temperature as a function of the… Expand
