日本新发现五种新氧化物超导体日本科学技术厅无机材料研究所的超导研究室最近发现多种氧化物超导体。有碳酸盐、硫酸盐、钡、铝、镓等五个种类的系列。新发现的超导体，都是在５０～６０亿Ｐａ的超高压环境下，在超过他们熔点１２００～１３００℃的高温下合成的。各系列... Five newly discovered oxide superconductors in Japan Superconductivity at the Institute of Inorganic Materials, Japan’s Department of Science and Technology has recently discovered a variety of oxide superconductors. There are carbonate, sulfate, barium, aluminum, gallium and other five kinds of series. The newly discovered superconductors are all synthesized at a superhigh pressure of 5 to 6 billion Pa at temperatures exceeding their melting point of 1,200 to 1,300 ° C. The series ...
