Spin Orbin Interaction Spectroscopy

Nanoscale imaging and control of a new type of magnetism

Published:17.12.24 — An international collaboration including EPFL scientists has for the first time been able to directly image the domains structure of a novel type of magnetism, called altermagnets. Using micro machining they could further create single domain states promising for applications.

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.
