27 August 2020
The cover is a representation of the "nanoneedle" pressing the surface of the iron-rhodium alloy, causing the magnetic state of the materials to change in a simple and localized way. By pressing on different areas of the material, researchers have managed to generate antiferromagnetic nano-islands embedded in a ferromagnetic matrix, a very difficult task with the current techniques available.
The method was developed by researchers at the ICMAB, UAB and the ALBA Synchrotron, in collaboration with the UB and ICN2. The technique locally modifies the properties of a metamagnetic material by applying local pressure to the surface of the material using nanometric needles, allowing a much more easy and local modification than current methods. The research opens the door to a more accurate and precise control of magnetic materials and allows to improve the architecture and capacity of magnetic digital memories.
