At Pohang University of Science and Technology, researchers have discovered that a process long used to grow stable metal nanoparticles on oxide surfaces does something far more profound: it simultaneously rewires both the electrical and magnetic identity of the host material. Through a phenomenon called exsolution, nickel ions escaping a perovskite crystal lattice trigger a thousandfold drop in electrical resistance and awaken room-temperature magnetism where none existed before. This is not merely a materials science curiosity — it is a demonstration that defects, long treated as flaws to be
