·我国的超导研究水平仍居世界前列。钆系超导体材料的临界电流密度已达每平方厘米6,000安培;钆系超导薄膜临界电流密度已达每平方厘米100万安培;研制的射频超导量子干涉器件测量弱磁的灵敏度达到亿分之二高斯;发现了零电阻时温度为132K(—141℃)和104k(—109℃)的铋铅锑锶钙铜氧翅导体,创造了临界温度的世界新纪录。·日本青山学院的科研人员新制成了由钕、铈和钡、铜氧化合物组成的新超导物质,其原子结构与
· China’s superconductivity research is still the highest in the world. The critical current density of gadolinium-based superconductor material has reached 6,000 amperes per square centimeter; the critical current density of gadolinium-based superconducting thin film has reached 1 million amperes per square centimeter; the sensitivity of the developed RF superconducting quantum interference device to measure weak field magnetism reaches to one hundred millionths Second Gauss; discovered the bismuth-lead-antimony-strontium calcium-copper-oxygen-finned conductor at 132K (-141 ℃) and 104k (-109 ℃) at zero resistance, creating a new world record in the critical temperature. · Aoyama Institute of Japan researchers made a new superconducting material composed of neodymium, cerium and barium, copper oxide compounds, the atomic structure and
