New publication on magnetic materials for adaptable electronics and brain-inspired computing

Magnetic materials with competing interactions are promising candidates for adaptable electronics and brain-inspired computing.

These materials display differently modulated phases that can be stabilized under very similar conditions, allowing to drive the stability of the system from one phase to the other at extremely low power. Silvia Damerio has investigated the origin of two coexisting modulated phases in antiferromagnetic CaFe₂O₄ in collaboration with the spintronics team of Bart van Wees. For that, so-called spin Hall magnetoresistance measurements needed to be performed in devices as small as 10 microns, which makes the detection of spin current injection even more challenging.

Congratulations to the whole team for this achievement and their publication in Advanced Electronic Materials.
