ADVANCED MATERIALS & PROCESSES | MARCH 2025 9 team’s results are an important step toward achieving scalable fabrication and utilization of superconductors in a wide range of applications. Examples include quantum computers, mass transit using magnetic levitation, and advanced medical diagnostic and treatment devices. uci.edu. QUASIPARTICLE DISCOVERY IMPACTS MAGNETISM Two scientists at the University of Missouri, Columbia, along with their teams of students and postdoctoral fellows, recently made a significant discovery on the nanoscale. They found a new type of quasiparticle that exists in all magnetic materials, regardless of strength or temperature. These new properties challenge what researchers previously assumed about magnetism, showing that it is not as static as once believed. “We’ve all seen the bubbles that form in sparkling water or other carbonated drink products,” says researcher Carsten Ullrich. “The quasiparticles are like those bubbles, and we found they can freely move around at remarkably fast speeds.” The team believes this discovery could help support development of a new generation of electronics that are faster, smarter, and more energy efficient. However, the scientists first need to determine how this finding could work into those processes. One field that could directly benefit from the new discovery is spintronics. While traditional electronics use the electrical charge of electrons to store and process information, spintronics uses the natural spin of electrons—a property intrinsically linked to the quantum nature of electrons. For example, a cell phone battery could last for hundreds of hours on one charge when powered by spintronics. “The spin nature of these electrons is responsible for the magnetic phenomena,” explains researcher Deepak Singh. “Electrons have two properties: a charge and a spin. So, instead Deepak Singh (right) works on spintronics with a graduate student in Singh’s lab.

It’s more efficient because the spin dissipates much less energy than the charge.” Singh’s group conducted the experiments while Ullrich’s team analyzed Singh’s results and created models to explain the unique behavior they were observing under powerful spectrometers at Oak Ridge National Laboratory. missouri.edu.
