Dr. Juliano Denardin, CEDENNA researcher and academic at the Department of Physics of the Universidad de Santiago de Chile, was the only Latin American scientist to present at the First International Symposium on Three-Dimensional Nanomagnetism, “3DMAG 2026”, held from July 13 to 17 in Vienna, Austria.
At the meeting, the researcher presented a study on how the curvature and geometry of nanometric structures can modify their magnetic behavior and open up new possibilities for data storage, sensor development and future computing technologies.
3DMAG 2026 was the first edition of this international symposium dedicated exclusively to three-dimensional nanomagnetism. The event brought together specialists in nanofabrication, magnetic characterization, theoretical modeling, spin topology, magnetization dynamics, spintronics and magnetic nanodevices.
Dr. Denardin valued the opportunity to take part in a meeting that brought together researchers from different countries. “It was an excellent opportunity to hear from leading scientists in nanomagnetism and spintronics, visit state-of-the-art laboratories, such as those of the 3DNANO group, talk with other researchers and discuss possible international collaborations,” he said.
Geometry to control magnetic structures
The CEDENNA researcher presented the work “Geometry-Stabilized Skyrmions and FORC Hall Analysis in Curved Pt/Co/Ta Nanodomes”, focused on the behavior of magnetic structures known as skyrmions on curved surfaces formed by nanodomes and coated with layers of platinum, cobalt and tantalum.
This line of research analyzes how incorporating new geometries and topologies into nanometric structures can produce physical behaviors not observed in flat or two-dimensional systems.
The study is related to the search for new ways to control extremely small magnetic structures by designing their geometry. Skyrmions are stable configurations of a material’s magnetic moments and are studied for their potential use as information units in future data storage and processing devices.
Research in three-dimensional nanomagnetism could contribute, in the future, to the development of information storage technologies, sensors, spintronic devices, unconventional computing and applications related to biomagnetism.
