Unexpected magnetism discovered

Unexpected magnetism discovered: What the team found was an unexpected magnetic order among the titanium atoms at an interface between strontium titanate and lanthanum manganite, which are both insulators in bulk," Okamoto said.
With today's nano-fabrication tools, scientists can develop artificial materials with controlled precision – almost atom by atom – of alternating very thin crystalline layers of different materials. The properties of these materials are determined by the structure of interfaces of the different materials and how atoms interact through the interfaces.
