The skyrmions are created in an ultra-high vacuum deposition chamber: Using sputter deposition technology, a team of Empa researchers has succeeded in producing distinguishable skyrmions within finely tuned, ultra-thin metal layers at room temperature. Image: Empa Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions - the future bits for "0" and "1" - can exist at room temperature, as they recently reported in the renowned . Many of us may still be familiar with the simple physical principles of magnetism from school. However, this general knowledge about north and south poles quickly becomes very complex when looking at what happens down to the atomic level. The magnetic interactions between atoms at such minute scales can create unique states, such as skyrmions.
