Researchers have discovered giant conductivity of nanometre-sized domain walls separating polar regions in a non-oxide ferroelectric material. The high sensitivity of these walls to applied magnetic fields enables gigantic switching of the sample resistance, thus providing a route to new nanoelectronic building blocks.
