PSI researchers have created a magnetic metamaterial made of long nanomagnets, arranged in a flat, honeycomb pattern. The arrangement of magnetisation in the synthetic material assumed very different states at different temperatures – just like molecules in ice are more ordered than in water, and are in turn more ordered in water than in steam.

Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state. This material made of nanomagnets might well be refined for electronic applications of the future - such as for more efficient information transfer.

(Image: PSI/Luca Anghinolfi) A synthetic material - created from 1 billion nanomagnets - assumes different aggregate states depending on the temperature: the so-called metamaterial exhibits phase transitions, much like those between steam, water and ice. This effect was observed by a team of researchers headed by Laura Heyderman from PSI.
