  • Frustrated magnets - Hall Effect clues to their discontent

    An experiment conducted has revealed an unlikely behavior in a class of materials called frustrated magnets, addressing a long-debated question about the nature of these discontented quantum materials. The researchers tested the frustrated magnets -- so-named because they should be magnetic at low temperatures but aren't -- to see if they exhibit a behavior called the Hall Effect. When a magnetic field is applied to an electric current flowing in a conductor such as a copper ribbon, the current deflects to one side of the ribbon. This deflection, first observed in 1879 by E.H. Hall, is used today in sensors...
