Qnami helps revealing new candidate for spintronics

Domains at the surface of the prototypical multiferroic antiferromagnet BiFeO3 (yellow and brown) and the resulting magnetic signature (blue to red scale) that could be measured for the first time using Quantilever MX.

In a recent publication in Nature Materials”, a group of French researchers was able to image and understand a novel type of chiral spin-textures occurring on BiFeO3’s domain-walls, which had never been observed before.

One of the challenge was that magnetism in these materials is extremely difficult to study due to the weak magnetic signals they usually generate. Using Qnami’s Quantilever MX, the team could overcome this limitation, confirm the results from the team’s simulations and validate their assumptions.

Qnami is a start-up from the University of Basel, Switzerland. By combining quantum technologies with the unique properties of synthetic diamonds, the company is able to design and produce non-invasive sensors with the world’s best sensitivity.
