Hidden magnetic spirals

At Quantum Sensing Lab (University of Basel) they are real experts at sensing magnetic fields. To prove it, and together with the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay they’ve just reported in Nature the visualization (in real space) of non-collinear antiferromagnetic order in a magnetic thin film at room temperature with nanometer resolution.

In particular, they’ve scanned Bismuth ferrite showing that exhibits a spiral magnetic ordering, with two superimposed electron spins. This might be particularly suitable for data storage devices because these materials magnetic fields can be easily modified using electric fields.
