On a breezy afternoon last autumn in Cambridge, Mass., in a laboratory thrumming with the huff-whish-huff sound of ...

Stabilising curve: The arrows show the remnant magnetisation of a toroidal nanomagnet. On the outer edge (the right) we can see a vortex where the magnetisation spirals inwards to a point. An ...

Research from the University of Minnesota Twin Cities gives new insight into a material that could make computer memory faster and more energy-efficient. The study was recently published in Advanced ...

Ferromagnets are characterized by a magnetization that has long been used to store information. The magnetization is largely due to localized electron spins with their associated magnetic moments ...

In their research, Hasenfratz, Catterall, and Butt used renormalization group (RG) theory to study the more complex phase ...
