Altermagnetism proves its place on the magnetic family tree

Published:21.02.24 — Thanks to experiments at the Swiss Light Source SLS, scientists of the Paul Scherrer Institute and EPFL and their international team have proved the existence of altermagnetism, a new addition to the magnetic family. This experimental discovery is reported in Nature and signifies new fundamental physics, with major implications for spintronics.

Charge fractionalisation observed spectroscopically

Published:08.05.24 — A research team led by EPFL professor Gabriel Aeppli and the Paul Scherrer Institute has spectroscopically observed fractionalisation of electronic charge in an iron-based metallic ferromagnet. Experimental observation of the phenomenon is not only of fundamental importance. Since it appears in an alloy of common metals at accessible temperatures, it holds potential for future exploitation in electronic devices. The discovery is published in the journal Nature.

Strange magnetic material could make computing energy-efficient

Published:01.11.23 — A research collaboration co-led by EPFL has uncovered a surprising magnetic property of an exotic material that might lead to computers that need less than one-millionth of the energy required to switch a single bit.
