Physicists Solve Mystery of “Frustrated Magnets” Through Hall Effect

A team of physicists from Princeton University performed an experiment on quantum material to determine discontentment in its nature.

Frustrated magnets are materials in which regular magnetic moments, interaction and spins cannot be satisfied concurrently. The main aim of the experiment was to check whether these magnets show Hall Effect or not.

Hall effects is a process in which magnetic field is applied to an electric current of conductor. The filed instantly changes path way of the current.  It is commonly noticed in charged particles. Hence, researchers believed that it is impossible to observe Hall Effect on neutral particles.

Phuan Ong, a professor of physics at Princeton, remarks that Hall Effect for neutral particles is an oxymoron.

Robert Cava, a professor of Chemistry at Princeton, along with his colleagues thought that Hall Effect might work on non-charged particle in cold condition.  They selected a class of magnets known as pyrochloers.  The magnetic moments of phychlores has the ability to line up in systematic way at low temperature. The arrangement usually forces magnetic moments to point at a single direction.  During the experiment, experts observed that magnetic moments are pointing in random directions.

Undoubtedly, the study reveals significant details regarding high-temperature superconductivity process.
