SLAC Exploring and manipulating the behavior of polar vortices in materials may lead to new technology for faster data transfer and storage. Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity. In 2016,...
