We have developed two novel organic superconductors kappa H- and kappa L-(DMEDO-TSeF)2Au(CN)4 (DMEDO-TSeF = dimethyl(ethylenedioxy)tetraselenafulvalene) with the onset transition temperatures of 4.8 K for the kappa H-phase and 3.0 K for the kappa L-phase at ambient pressure, where DMEDO-TSeF is the second example following tetramethyltetraselenafulvalene (TMTSF) after an interval of 25 years as a sulfur-free donor providing a bulk organic superconductor.
我们已经合成了两种新型有机超导体κH-和κL-(DMEDO-TSeF)2Au(CN)4(DMEDO-TSeF = 二甲基(乙二氧基)四硒富瓦烯),在环境压力下,κH相的起始转变温度为4.8 K,κL相为3.0 K,其中DMEDO-TSeF是继四甲基四硒富瓦烯(TMTSF)之后时隔25年作为提供体相有机超导体的无硫供体的第二个例子。
