Superconductivity is a phenomenon of zero electrical resistance, and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature. The usual temperature is very close to absolute zero and far from room conditions. So the key is finding a ways to increase that temperature as high as one can. A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties—in particular, the ability to transport much more electrical current than non-engineered materials.
