Albert Fert, Mairbek Chshiev, André Thiaville and Hongxin Yang, J. Phys. Soc. Jpn. 92, 081001 (2023).   In this Review article, the authors briefly introduce the research history of DMI and its significance in the field of modern spintronics. Since the early 1960’s, the discovery of Dzyaloshinskii–Moriya interaction (DMI) helped to explain the physical mechanisms […]

A new type of magnetic sensor based on the spin transfer torque using 50-100nm diameter perpendicular magnetic tunnel junctions was recently reported in the IEEE Sensors Journal. The paper demonstrates the magnetic field sensing principle, patented by Spintec in 2020, while also describing possible read-out methods and their associated signal conditioning electronics. Improvements over conventional […]

The Dzyaloshinskii–Moriya interaction (DMI) arising in the magnetic systems with broken inversion symmetry plays an essential role in topological spintronics. Using atomistic spin model simulations of an intriguing type of DMI emerging in the films with composition gradient (g-DMI), it is demonstrated that that both the strength and chirality of g-DMI can be controlled by […]

Magnetic skyrmions are localized chiral spin textures, which offer great promise to store and process information at the nanoscale. The unique sense of rotation of their surrounding domain wall, called chirality, is resulting from the so-called Dzyaloshinskii−Moriya Interaction. C.E. Fillion et al. have managed the inversion of the skyrmion chirality by applying a gate voltage, […]

Skyrmions in synthetic antiferromagnets are appealing for use in future memory and computing devices, combining small size and fast motion, but creating, stabilizing, and observing them remains a challenge. Here, we demonstrate the stabilization and current and light induced nucleation of skyrmions in a synthetic antiferromagnet, observing the magnetization texture in each layer using X-ray […]

A new form of spintronic is emerging, exploiting electrical insulators. Recent spectroscopic studies performed at SPINTEC have revealed the coherent coupling that may establish between two distant macrospins separated by a non-magnetic dielectric spacer via circularly-polarized acoustic phonons that carry angular momentum information. This long-range effect represents an important progress in magnonics and spin wave […]
