苏联科学家在世界上首先使用高温超导体测得人心跳产生的微磁场。这种技术的公开实验已促进科学界对高温超导体实际应用的机会恢复信心。莫斯科杜布纳的联合核研究所的鲍里斯·瓦西里耶夫已把他的工作的详细报告寄给了在伯明翰大学半导体研究小组的领导人柯林·高夫。上周,高夫原定要在谢菲尔德的英国协会会议上阐述有关高温超导的可能带来的机会问题,而上述消息恰好在他发言前送到。瓦西里耶夫使用了钇、钯、铜和氧的化合物(YBa_2Cu_3O_7)制成一种称为SQUID的装置——即超导量子干涉仪。这是一种超导材料环,它对于垂直穿过环的磁通变化非常敏感。瓦西里耶夫的装置被称为“块体”射频SQUID。它的环是由一大块超导材料构成,其
Soviet scientists in the world first use of high-temperature superconductor to measure the micro-magnetic field generated by human heart. Public experiments with this technology have encouraged the scientific community to restore confidence in the practical application of HTS. Boris Vasiliev, of the Joint Nuclear Institute at Dubna, Moscow, has sent a detailed report of his work to Colin Gough, the leader of the semiconductor research group at the University of Birmingham. Last week, Gough was originally scheduled to speak at a British Association meeting in Sheffield about potential opportunities for high-temperature superconducting, delivered just before he spoke. Vasiliev uses yttrium, palladium, copper and oxygen compounds (YBa 2 Cu 3 O 7) to make a device called a SQUID - a superconducting quantum interferometer. This is a ring of superconducting material that is very sensitive to changes in flux perpendicularly across the ring. Vasiliev's device is called a “bulk” RF SQUID. Its ring is made of a large piece of superconducting material
