A New Magnet in a Uranium Compound
Scientists have found many new discoveries in uranium over the past decades- one of which happens to be a new type of magnet. The magnet, called USb2, which is composed of uranium and antimony, is a singlet-based magnet that generates magnetic energy in a way no other magnet has done before. All magnets contain electrons, which are tiny particles than generate their own small magnetic fields, containing a north and south pole.
In most cases, the magnetic fields will point in random directions, canceling each other out-and is also the reason why many objects aren’t just huge magnets. In some metals though, the magnetic fields are aligned and and create a strong and powerful magnetic field that has the capability to move other metals around and manipulate them. The previous example is how all scientists thought magnets worked, from car magnets to even the Earth itself, until now.
The newly discovered magnet has electrons that tend to not have aligned magnetic fields, so it can’t generate magnetic energy using the total strength of the electrons. But the electrons in the magnet can work together to create quantum-mechanical objects classified as “spin excitons”. These particles are different than electrons and protons and neutrons because they aren’t actually individual, but instead act like they are, called quasiparticles. Spin excitons form from the interaction of electrons, and therefore a magnetic field is created.
In the future, scientists say this new type of magnet could prove to be very useful in the age of technology. Many computers used today contain magnets that switch back and forth to transmit information. The new singlet magnet is actually very efficient in switching back and forth from magnetized to an unmagnetized state than other magnets as analyzed by scientists. It’s a possibility that devices containing singlet magnets could perform and run faster than electronic devices containing regular magnets in the future.
