Magnetism directs atoms: breakthrough in nanophysics!
In a groundbreaking study, scientists from the Christian Albrechts University in Kiel (CAU) and the University of Hamburg have shown that magnetism can influence the movements of individual atoms on surfaces. These findings, which were published in the journal Nature Communications , show that atoms such as cobalt, rhodium and iridium move along with coincidental, but along magnetic rows when they are applied to a specially prepared manganese layer. The experiment was carried out at extremely low temperatures of four Kelvin, almost the absolute zero point to record the complex interactions. Uni Kiel reports that this movement was observed even in non-magnetic atoms.The underlying mechanisms that influence the direction of movement of the atoms were determined with quantum mechanical invoices on supercomputers. The simulations show that it is energetically cheaper to move along the magnetic rows. This discovery opens up new perspectives for applications in nanotechnology, data storage and material development, since the targeted control of nuclear movements could lead to improved performance in these areas.
research at the interface of nanophysics and magnetism
The research focuses at the Free University of Berlin, which has been associated with nanophysics and surface physics for decades, are wide and include the examination of materials at the nuclear level. Examples are molecules as switches, vans or nanomotors as well as the examination of two -dimensional graphs and one -dimensional carbon nanor tubes. The use of raster probe techniques for manipulating nuclear structures is crucial for the understanding of quantum mechanical effects in these systems. fu berlin emphasizes how fundamental these effects are for the development of new technologies.
In addition, the Karlsruhe Institute of Technology (KIT) offers extensive programs in nanophysics that combine both theoretical and experimental approaches. Scientists at the KIT are working on researching nanosystems with a variety of methods, including electron microscopy and grid proboscopy. The central lecture series "Fundamentals of Nanotechnology" illustrates the relevance of quantum physics when determining various material properties and the occurrence of unusual effects. kit makes it clear that the examination of molecular interface changes is essential for the molecular electronics.
future applications and developments
The combination of the new findings about magnetic interactions and the existing research approaches in the field of nanophysics lays the foundation for future developments in technology. The ability to control nuclear movements could have a basic impact on the development of innovative materials that are used in information storage and other technological fields. Research is thus on the threshold of significant progress that could revolutionize the design and understanding of materials on the nanoscale level.
