Fast-moving magnetic particles could enable new form of data storage
Massachusetts Institute of Technology
Researchers from MIT and Germany have shown that virtual particles known as skyrmions, discovered just a few years ago, hold promise as a new way of storing data -- one that could overcome fundamental limits that might otherwise be signaling the end of 'Moore's Law.'

The observation of the spin Nernst effect in platinum thin film is reported. This and the spin Hall effects are found to be of similar magnitude.
A tuned oxide superlattice possesses two coexisting phases — one ferroelectric, the other with vortex order — which can be interconverted under electric field, changing material properties.
Zirconium nanoparticles introduced into aluminium alloy powders control solidification during 3D printing, enabling the production of crack-free materials with strengths comparable to the corresponding wrought material.
