Increasing the thermal budget beyond 400°C of magnetic random access memory (MRAM) cells is a major goal to allow for seamless conventional electronics integration. At these temperatures significant material diffusion can destroy the interface properties of new generation perpendicular magnetization stacks targeting technology nodes below 20nm. This study highlights the origin in the improvement obtained […]

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 […]

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 […]

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 […]

The conceptual proposal for a so-called race-track three-dimensional data storage device based on domain walls in a dense array of vertical wires, revived the attention on cylindrical magnetic nanostructures. While mostly nanowires have been considered so far, nanotubes, i.e. a shell with an empty core, would open the door to core-shell structures, whose interfaces could […]

Magnetic skyrmions are topologically nontrivial magnetic domains where the magnetization rotates in a fixed sense (chirality). They are usually created by magnetic fields or by non-homogeneous electric currents. Here S.G. Je et al. have shown that hexagonal skyrmion bubble lattices can be locally generated with ultrafast (30 fs) laser pulses. Their original optical approach to […]

A complete set of the generalized drift-diffusion equations for a coupled charge and spin dynamics in ferromagnets in the presence of extrinsic spin-orbit coupling is derived from the quantum kinetic approach, covering major transport phenomena, such as the spin and anomalous Hall effects, spin swapping, spin precession, and relaxation processes. It is argued that the […]

Despite being a weak spin–orbit coupling material, graphene demonstrated to induce significant Dzyaloshinskii–Moriya interaction due to the Rashba effect leading to formation of chiral spin textures in adjacent ferromagnet (FM) at graphene/FM interfaces. First-principles calculations and experiments using spin-polarized electron microscopy show that this graphene-induced Dzyaloshinskii–Moriya interaction can have a similar magnitude to that at […]

Due to the nanometer size of magnetic tunnel junctions and high interfacial resistance of ultrathin MgO tunnel barriers, temperature modulation at GHz frequency can be achieved in these devices and efficiently use to amplify microwaves in spintronics oscillators. Spintronics oscillators use two major phenomena discovered in spin-electronics: the tunnel magnetoresistance of magnetic tunnel junctions (MTJ) […]
