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

In a series of experiments published in Nature Physics, researchers from Japan, the UK, Sweden, and the Czech Republic collaborated at ILL-IN15, one of the world's leading spin echo facilities. Their neutron spin echo (NSE) experiments confirmed the presence of asymmetric dynamics in the skyrmion phase of MnSi, indicating its strong potential for spintronic devices and sustainable technology.

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.
