For the first time, researchers have succeeded in using X-rays to capture a three-dimensional image of a magnetic skyman. This development could pave the way for a new generation of storage media and minicomputers.
The SkyrmionsSkyrmions They could represent a major breakthrough for information storage and quantum computers in particular, but these quasi-particles are particularly difficult to study. For the first time, a team of American and Swiss researchers has managed to capture a 3D image of a magnetic skyman.
But what exactly is it? Magnetic skyrmions are of the type. walk aroundwalk around Magnetism at the nanoscopic scale is, more precisely, Skymanus vortices. rotaterotate d’ElectronElectron Adversaries, incl movementmovement can be controlled by an electric charge or a. Magnetic fieldMagnetic field. Until now, they were thought to be two-dimensional disks, but the image obtained by the researchers has been published in the journal. Advances in scienceshows that the structure is three-dimensional.
Towards spintronics and minicomputers
The researchers were able to observe using a magnetic skyrman. X-rayX-ray 800 on disk NanometerNanometer in diameter and 95 nanometers thick. To do this, they used a soft X-ray luminography technique to record a series of images as the object was rotated. They then used algorithms to combine these images and create a 3D representation with voxels (the 3D equivalent of pixels) 20 nanometers on a side.
A better knowledge of the Skymens will especially allow progress in this. SpintronicsSpintronicsthe branch of electronics that exploits the spin of electrons. Skyrmions have the advantage of being very stable and fast, and can use much smaller magnetic bits than hard drives. This would pave the way for currently used high-density storage media and much more energy-efficient minicomputers.
