#New material science research may advance tech tools The researchers manipulated a steel gray mineral called manganite, which is used to build magnetic hard discs in computers. They created holes, or antidots, in thin films of manganite. It was discovered that the edges of the antidots were magnetic.""The discovery of the magnetic edge states on the antidots made this work possible. Nobody had seen ever this before,"said LSU Physics Professor Ward Plummer, a co-author on the study. The magnetic phase state at the edges of the antidots raised the metal-to-insulator phase transition temperature of the manganite film. The researchers were able to replicate this through simulations.""People have tried really to increase the temperature and reduce the operating field or tried to change the substrate or chemical composition. But we find this new approach with antidots to be said quite useful Jian Shen, head of the Department of physics at Fudan University and a co-author on the paper.""What you really would like to do is get this temperature above room temperature, so you can switch the material by using a magnetic field, "Plummer said d
