Researchers from the University of Augsburg and ETH Zurich 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. Such behaviour is unprecedented in non-oxides, which are less hampered by defects and deviations in composition than oxides.
