Working with the smallest magnets, the Hebrew University discovered a new magnetic phenomenon with industrial potential.
For physicists, exploring the kingdom in a very small area is a great country. Brand new and unexpected phenomena have been discovered (New magnetic phenomenon with industrial potential). At the nanoscale, where materials as thin as 100 atoms are being studied. Nature ceases to behave here as predicted by the macroscopic laws of physics. This is unlike what is happening in the world around us or beyond. Dr. Yonathan Anahory of the Hebrew University of Jerusalem (HU) at the Racah Institute of Physics led a team of researchers, including a doctoral student from HU, Avia Noah. He expressed his surprise when he looked at images of magnetism generated by nanomagnets. “This is the first time we’ve seen a magnet move this way,” he described that the images revealed the event in “Edge Magnetism.”
The images show that the magnetic material studied by HU researchers retains magnetism only at the edge. In fact only it is up to 10 nanometers from the edge (remember that human hair is about 100,000 nanometers). Their results were recently published by the prestigious magazine Nano Letters.
This nano effect, although very small, can have many applications in our daily lives. “In today’s technology race to make each component smaller and more energy efficient, we focus on small magnets with different shapes,” says Anahory. The new edge magnetism offers the possibility to produce long wire magnets with a thickness of only 10 nanometers, which can be curved into any shape. “It could change the way spintronic devices are made,” Anahory said. He referred to next-generation nanoelectronic devices with reduced power consumption and more memory as well as processing capacity.
The real discovery of fringe magnetism is somewhat surprising. Anahory decided to look at a new magnetic nanomaterial (CGT) created by his colleague at the Universidad Autónoma de Madrid in Spain. The discovery is ultimately based on images created by a new type of magnetic microscopy developed in Israel. The magnetic microscopy can measure the magnetic field of an electron. The discovery of new phenomena is based on more sophisticated new technologies. In addition, the miracles themselves will be at the center of more advanced technologies, as proven by marginal magnetism.
