Hall Effect Observed in Frustrated Magnets For the First Time

Researchers from Princeton University carried out an experiment on “frustrated magnets” through Hall Effect.

Frustrated magnets are materials in which spins, moments and interactions cannot be contented simultaneously. Previously, experts believed that the materials are a low temperature magnet. However, latest study rebuffs all the previous misconceptions.

The main aim of researchers was to determine the reason behind “discontent” nature of Hall Effect. It is a process in which a magnetic field is applied to an electric current.  The field forces magnet to bend to the other side of semi-conductor. The effect commonly occurs in charged particles and used for electronic devices like quantum computing. It allows researchers to perform numerous calculations at the same time.

The team of researchers speculated that Hall Effect can also emerge in non-charged like neutrons and frustrated magnets. They believed that neutral particles can exhibit Hall Effect in extremely cold temperature.

Phaun Ong, a professor at Physicist at Princeton, talked about frustrated magnets. He informs that these materials are quite interesting. Experts believe that the material can easily spin, but the spin is entangled because of geometric frustration.

Hence, researchers utilized a type of magnets known as pyrochlores in the experiment. They attached small electrodes on both sides of the crystals. Afterwards, they utilized microheaters to send heat through them. The entire experiment was carried out at extremely low temperature. Astonishingly, researchers noticed that hall effect on one side of the material.

Ong stated that everyone was shocked to see the outcome of experiment.
