Scientists of Far Eastern Federal University (FEFU) with international collaborators have proposed direct magnetic writing of skyrmions, i.e., magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information and produce topological patterns with a resolution less than 100 nanometers. This has applications for miniaturized post-silicon electronics, new topological cryptography techniques and green data centers, potentially reducing the load on the Earth's ecosystem significantly. A related article appears in ACS Nano.
