Autor: Haozhe Yang, Eva Schmoranzerová, Pyunghwa Jang, Jayshankar Nath, Thomas Guillet, Isabelle Joumard, Stéphane Auffret, Matthieu Jamet, Petr Němec, Gilles Gaudin, Ioan-Mihai Miron
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-7 (2022)
Many recent studies have explored the response of magnetic systems to circularly polarised light. To achieve this, typically experiments use a birefringent crystal. Here, Yang et al show that any small error in the alignment of the crystal can result

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-8 (2022)
A major feature defining the motion of magnetic spin textures is the chirality or ’handedness’ of the spin texture, which in turn depends on the underlying material. Normally it is considered as fixed, but in this article Fillion et al demonstrat

Fabrication of nanotweezers and their remote actuation by magnetic fields
Autor: Cécile Iss, Guillermo Ortiz, Alain Truong, Yanxia Hou, Thierry Livache, Roberto Calemczuk, Philippe Sabon, Eric Gautier, Stéphane Auffret, Liliana D. Buda-Prejbeanu, Nikita Strelkov, Hélène Joisten, Bernard Dieny
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-9 (2017)
Abstract A new kind of nanodevice that acts like tweezers through remote actuation by an external magnetic field is designed. Such device is meant to mechanically grab micrometric objects. The nanotweezers are built by using a top-down approach and a

International audience; To improve the read/write margin in perpendicular spin transfer torque magnetic random access memory (STT-MRAM), a concept of the double-magnetic tunnel junction (MTJ) MRAM cell is proposed in which the STT efficiency can be c

Publikováno v: Sports Medicine - Open, Vol 10, Iss 1, Pp 1-10 (2024)
Abstract Background In contrast with Advanced Footwear Technology-AFT running shoes for long-distance, little is known about AFT sprint spikes on performance and acceleration parameters. However, their use has become widespread since the Tokyo 2020 O

Nanoscale, Royal Society of Chemistry, 2021, 13 (26), pp.11488-11496. ⟨10.1039/D1NR00346A⟩
In this study, a new type of compact magnetic memristor is demonstrated. It is based on the variation of the conductivity of a nano-sized magnetic tunnel junction as a function of the angle between the in-plane reference layer magnetization and a fre
