Recently, a remarkable breakthrough has been achieved by Professor Zhao Weisheng and his research team at the School of Integrated Circuit Science and Engineering, Beihang University, in the realm of electrically controlling exchange bias. The team has ingeniously devised a novel approach that leverages single carbon nanotubes for patterning without the need for traditional lithography techniques. This innovative method has successfully demonstrated the stable presence of the exchange bias effect at an incredibly fine scale of 8.66 nanometers, marking a significant milestone in achieving electrical control at such minuscule dimensions. The findings of this groundbreaking research have been featured in the prestigious international journal Nature Communications, with the research paper aptly titled "Electrical control of exchange bias in sub-10 nm regime enabled by single-nanotube patterning".
