日本夏普公司中央研究所新近发现在弱磁场下钇钡铜氧系陶瓷超导材料具有电阻值变化极大的特性,并利用这种现象第一个研制成功了一种高性能磁传感器—超导磁阻元件。目前,对陶瓷超导体的研究主要是提高临界温度、临界磁场、临界
Japan Sharp Corporation Central Research Institute has recently found that in a weak magnetic field yttrium barium copper oxide ceramic superconducting materials have great resistance characteristics, and the use of this phenomenon was the first successful development of a high-performance magnetic sensor - superconducting Magnetoresistive element. At present, the research on ceramic superconductors mainly increases critical temperature, critical magnetic field and criticality
