Exotic Metal Found to Exhibit Giant Hall Effect Without any Magnetic Field

A magnetic field can deflect an electric current. In the case of conducting materials, this results in what is called the Hall effect, which is usually used to quantify magnetic fields.

Scientists at TU Wien, working with researchers from the Paul Scherrer Institute (Switzerland), McMaster University (Canada) and Rice University (United States), have now achieved a fascinating discovery: an exotic metal composed of cerium, palladium and bismuth was investigated and the material was found to produce a giant Hall effect, in the complete absence of any magnetic field.
