New 2D quantum sensor breakthrough offers new opportunities for magnetic field detection Date: May 29, 2025 Source: University of Cambridge Summary: Physicists have unveiled a breakthrough in ...

Instead of focusing on sensor readings at specific points, their magnetoreceptor captures electrical resistance information ...

Researchers from the Niels Bohr Institute have now succeeded in developing a method for extremely precise measurements of such ultra-small magnetic fields with an optical magnetic field sensor.

The limitations of diamond-based sensors, though, is that they can only detect magnetic fields when aligned in the direction of the field. If unaligned, they have large blind spots.

In contrast, the hBN sensor developed by the team in Cambridge does not share these limitations and instead presents a multi-axis sensor of magnetic field with large dynamic range.

The state of such systems is sensitive to magnetic fields, temperature and pressure and can therefore be used as sensors for all of these.

An application note from an IEEE Magazine shows that STT-MRAM memories should be able to achieve high densities with simple precautions in normal ambient magnetic fields.

Physicists found that speeding electrons trapped in circular loops in graphene quantum dots are highly sensitive to external magnetic fields.

Quantum sensors often rely on power-hungry lasers to make measurements. A new quantum magnetometer uses sunlight to measure magnetic fields instead.
