Could skyrmions solve the baryogenesis problem?
Magnetic nanoparticles known as skyrmions and their antiparticle equivalents can behave very differently, according to new calculations by researchers in Sweden, Germany and France. This unexpected new finding could have important consequences for any potential technologies involving these particles, such as new generation data storage and information processing devices.
Skyrmions are swirling vortex-like magnetic spin structures that extend across a few nanometres in a material and can be likened to 2D knots in which the magnetic moments rotate about 360° within a plane. They are now known to occur in many materials and were first observed in experiments about 10 years ago. They show much promise as the building blocks for next...
