Scientists unravel 'Hall effect' mystery in search for next generation memory storage devices

"weak external magnetic field... tunable stress... applying stress to Weyl antiferromagnet... residual external magnetic field increased.... If the magnetic field were driving the Hall effect, there would be a corresponding effect on the voltage across the material. The researchers showed that, in fact, the voltage does not change substantially, proving that the magnetic field is not important. Instead, they concluded, the arrangement of spinning electrons within the material is responsible for the Hall effect"
