Student Research: Researchers develop ultra-sensitive device for detecting magnetic fields

June 9, 2020

A team of Brown University physicists, including doctoral Physics student Yiou Zhang, has developed a new type of compact, ultra-sensitive magnetometer. The new device could be useful in a variety of applications involving weak magnetic fields, the researchers say. “Nearly everything around us generates a magnetic field — from our electronic devices to our beating hearts — and we can use those fields to gain information about all these systems,” said Gang Xiao, chair of the Brown Department of Physics. The new device is detailed in a paper published in Applied Physics Letters.
