Polarised inelastic neutron scattering on IN20 directly revealed, for the first time, opposite-handed magnons in an altermagnet and showed that their chirality can be reversibly switched

Des chercheurs du Japon, du Royaume-Uni, de Suède et de République Tchèque ont mené une série d'expériences cruciales à l'ILL sur l'instrument IN15, une installation de pointe pour l'écho de spin. Leurs travaux, publiés dans Nature Physics, ont utilisé l'écho de spin neutronique (NSE) pour confirmer une dynamique asymétrique dans la phase skyrmion du MnSi. Cette découverte souligne le fort potentiel du MnSi pour les dispositifs spintroniques et les technologies durables.

Though continuous down-scaling in microelectronics has enabled the industry to achieve phenomenal success, the trend is now approaching fundamental limits. Promising alternative technologies for next generation devices exploit not only the charge of the electron – as used in conventional microelectronics – but also the electron spin (spintronics) or spin waves (magnonics) in order to transmit, st…

Neutrons throw light on an important manufacturing process in the textile industry.

Understanding, manipulating and exploiting the intriguing magnetic behaviour of a synthetic crystalline material called yttrium iron garnet (YIG) could open the door to the next, advanced generation of communication and information-processing devices. Experiments at the Institute Laue-Langevin (ILL) neutron beam facility in Grenoble, France have for the first time fully exposed the complex magnetic behaviour of YIG.
