Seminar – skyrmions in the Zero-Magnetisation Limit

On Friday April 5, we have the pleasure to welcome Laurent Ranno from Néel Institute, he will give us a talk at 14:30, CEA/SPINTEC, Bat 1005, room 434A entitled : Skyrmions in the Zero-Magnetisation Limit Skyrmions have been experimentally observed in several ultrathin film systems. I will describe them, compare them, using the same model, […]

PhD topic – Spintronics on magnetic skyrmions at Spintec

Spintec invites application for a phd thesis position in spintronics on magnetic skyrmions. Magnetic skyrmions are nm scale topological spin texture that hold great promise for storing and manipulating the information at the nanoscale. Spintec recently demonstrated magnetic skyrmions at room temperature in ultrathin nanostructures [1] as well as their manipulation using electric field [2,3] […]

PhD position – Exploring the scalability of spintronics for 3D devices

Topic Classical microelectronics is reaching its limits of downward scalability, reaching technological or scientific bottlenecks. Magnetic random access memories, based on magnetic tunnel junctions storing and reading bits of information, are emerging key ICT components. They are of immediate relevance for low-power and high-speed processor and mass-storage cache memory. Similar to other technologies, ways are […]

A generic probe for spin fluctuations in nanometer-scale films

In the field of spintronics, which relies on the spin-dependent transport properties of matter, exploring spin fluctuations and phase transitions in ultrathin films is essential as it provides key information to engineer materials for applications. Here, O. Gladii et al investigated the generic character of a novel method to probe spin fluctuations through demonstration with […]

Impact of heating on the stability phase diagrams of perpendicular MTJs

Measured switching diagrams of perpendicular magnetic tunnel junctions exhibit unexpected behavior at high voltages associated with significant heating of the storage layer. The boundaries deviate from the critical lines corresponding to the coercive field, which contrasts with the theoretically predicted behavior of a standard macrospin-based model. In this paper, we are proposing a modified model […]

A Route towards Dynamic Control of Skyrmion Chirality

The very popular magnetic bubbles called skyrmions are promising for dense data storage, logic and neuromorphic applications thanks to the unique sense of rotation (chirality) of their surrounding domain wall. The so-called Dzyaloshinskii−Moriya Interaction (DMI) is crucial for their stability. Here, T. Srivastava et al. have shown that DMI can be dynamically and locally controlled […]
