Two professors of Tokyo Institute of Technology developed a new superconductive material whose electric resistance becomes zero should it be cooled down at a low temperature. The new material has two layers that pile up alternately: A layer where electricity flows without resistance and a layer where electricity flows slowly with resistance. It seems to be helpful for the development of a new type arithmetic element of an ultrahigh-speed computer. This is the result of the joint research by Tokyo Institute of Technology and National Institute for Materials Science. The new material is a bedded compound made of bismuth, nickel, and cerium. The superconductive phenomenon happens at 269 degrees centigrade below zero. Improving the kinds and organization of elements may enable the superconductive phenomenon to happen at a higher temperature. It may be possible to develop a new type arithmetic element that stores data in the layer with electric resistance and transmits data in the layer without electric resistance. The result was presented in the February 2, 2011 issue of the journal of American Physical Society.
