A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a compact dynamic cantilever magnetometer with a diameter of just 22 mm, achieving magnetic moment sensitivity on the order of 10^-17 A·m².

“This breakthrough fills a technological gap in ultra-sensitive magnetic measurements for small, low-dimensional materials under high magnetic fields,” said Prof. Wang Ning, a member of the team.

The study was published in Review of Scientific Instruments.
