swirls

image: A magnetic vortex, known as a skyrmion (gray dot), moved around the corners of a triangular field by electric currents, where it bounces around the sides. The potentials shown in red are sufficient to perform Boolean logic operations. see After Credit: ill./©: Klaus Raab, JGU Much of the energy used today is consumed in …

Three-dimensional diagram of the device. The stack structure is shown in the lower circle. Attached are the chrome/gold contacts, to which a positive, negative or zero potential can be applied. The input values ​​used for this Boolean logic demonstration are highlighted in red. The dark gray spot within the triangle represents a skyrmion as imaged …
