The world of quantum materials continues to expand and this time scientists are learning about magnets. Or rather, they have learned that magnets can be frustrated like a child who doesn’t get his way.
It is an interesting experiment to say the least, but one that will most likely add yet more compelling data to the behavior of quantum materials. Indeed, the study—which was published just this week in the journal Science—may lend some new insight into the future of more sophisticated electronics and the mechanisms of higher-temperature superconductivity (the so-called frictionless transmission of electricity).
The term “frustrated magnet” refers to magnets which should be magnetic at low temperatures but are not. Perhaps, “defiant” is another way to describe them. In this experiments, scientists wanted to see if these new magnets would exhibit a physical behavior known as the “Hall Impact.” This behavior is categorized by a magnetic field applied to an electric current flowing within a conductor (like, perchance, a copper ribbon) which then causes that conductor (ie, the ribbon) to deflect to one side of the conductor.

Obviously, this effect is named after its first person to observe the behavior, E.H. Hall (in 1879), and it is used quite often today in sensors for such devices as personal computer printers as well as anti-lock brake systems in automobiles.
But the Hall Impact is typically associated with charge-carrying particles and these physicists wanted to know if the same behavior would occur in non-charged (neutral) particles like those found in “frustrated magnets.”
And, to make a long story short, the researchers found that, at certain moments, when conditions are just so, the Hall Impact can, in fact, exist even for frustrated magnets.
