Researchers Discover New Method to Control Magnons for Advanced Electronics

Revolutionizing Magnetic Energy for Next-Gen Electronics

Thin-film heterostructures composed of Sr₂IrO₄, as documented in Nature Communications (2025). DOI: 10.1038/s41467-025-58922-z


A new investigation by researchers at the University of Kentucky is reshaping scientific understanding and manipulation of magnetic energy—and may pave the way for faster, more efficient electronic devices.

Study Led by Professor Ambrose Seo and Published in Nature Communications

Professor Ambrose Seo, Ph.D., of the University of Kentucky's Physics and Astronomy Department, led the research now published in Nature Communications.

Understanding Magnons and Their Role in Magnetism

What Are Magnons?

This investigation explores magnons—subtle ripples that facilitate the flow of magnetic energy throughout different substances.

"Magnons can be envisaged as clusters of electrons 'dancing' collectively within a magnet," explained Seo. "When electrons move in synchrony, their motion generates wave-like disturbances known as magnons."

The Difficulty in Controlling Magnons—Until Now

The scientific community has been investigating methods to harness magnons, envisaged as key components in tomorrow's high-speed computing and low-energy electronics. Yet, mastery over them had been out of reach—until now.

Strontium Iridium Oxide: The Game-Changing Material

Employing the uniquely magnetic strontium iridium oxide, Professor Seo's team explored how its proximity to metals or insulators altered magnons, making them 'softer' and thus less energy-intensive to mobilize.

"To put it plainly," remarked Seo, "The electrons altered their 'routine' based on the neighboring  material."

Structural Vibration and Magnetic Energy Control

The researchers suggest this effect arises due to the interaction between magnons and structural vibrations within the material—muck like the propagation of sound waves through air. Gaining clearer insight into and mastery over, these interactions may pave the way for novel methods of controlling magnetic energy, a crucial advance for future electronics.

Faster More Efficient Electronics on the Horizon

This advancement may result in swifter data handling, lower energy demands and extended battery performance in common electronic items like mobiles, laptops and smart wearables.

A New Frontier in Spin Wave Technology

"In the long run, this work could open the door to quicker and more efficient electronics by utilizing these oscillating electron spin waves," stated Seo.

NASA chile scientists comet 3i atlas nickel mystery

NASA and Chilean Scientists Study 3I/ATLAS, A Comet That Breaks the Rules Interstellar visitors are rare guests in our Solar System , but when they appear they often rewrite the rules of astronomy. Such is the case with 3I/ATLAS , a fast-moving object that has left scientists puzzled with its bizarre behaviour. Recent findings from NASA and Chilean researchers reveal that this comet-like body is expelling an unusual plume of nickel — without the iron that typically accompanies it. The discovery challenges conventional wisdom about how comets form and evolve, sparking both excitement and controversy across the scientific community. A Cosmic Outsider: What Is 3I/ATLAS? The object 3I/ATLAS —the third known interstellar traveler after "Oumuamua (2017) and 2I/Borisov (2019) —was first detected in July 2025 by the ATLAS telescope network , which scans he skies for potentially hazardous objects. Earlier images from Chile's Vera C. Rubin Observatory had unknowingly captured it, but ...

Quantum neural algorithms for creating illusions

Quantum Neural Networks and Optical Illusions: A New Era for AI? Introduction At first glance, optical illusions, quantum mechanics, and neural networks may appear unrelated. However, my recent research in APL Machine Learning Leverages "quantum tunneling" to create a neural network that perceives optical illusions similarly to humans. Neural Network Performance The neural network I developed successfully replicated human perception of the Necker cube and Rubin's vase illusions, surpassing the performance of several larger, conventional neural networks in computer vision tasks. This study may offer new perspectives on the potential for AI systems to approximate human cognitive processes. Why Focus on Optical Illusions? Understanding Visual Perception O ptical illusions mani pulate our visual  perce ption,  presenting scenarios that may or may not align with reality. Investigating these illusions  provides valuable understanding of brain function and dysfunction, inc...

fractal universe cosmic structure mandelbrot

Is the Universe a Fractal? Unraveling the Patterns of Nature The Cosmic Debate: Is the Universe a Fractal? For decades, cosmologists have debated whether the universe's large-scale structure exhibits fractal characteristics — appearing identical across scales. The answer is nuanced: not entirely, but in certain res pects, yes. It's a com plex matter. The Vast Universe and Its Hierarchical Structure Our universe is incredibly vast, com prising a p proximately 2 trillion galaxies. These galaxies are not distributed randomly but are organized into hierarchical structures. Small grou ps ty pically consist of u p to a dozen galaxies. Larger clusters contain thousands, while immense su perclusters extend for millions of light-years, forming intricate cosmic  patterns. Is this where the story comes to an end? Benoit Mandelbrot and the Introduction of Fractals During the mid-20th century, Benoit Mandelbrot introduced fractals to a wider audience . While he did not invent the conce pt —...
