【摘要】 我们研制了YBa₂(Cu_1-xSn_x)3O_7-δ超导体,其中 x=0.01,0.02,0.03,0.04,0.05.发现当 x=0.03时,零电阻温度达92K.但是经过适当剂量中子和γ-射线辐照后,该样品零电阻温度达101.4K.更多还原

【Abstract】 The general formulaYBa2(Cu1-xSnx)3O7-δ,whrer x=0.01,0.02,0.03,0.04,0.05,is discussed.We observed that the temperature of zero resistance was 92K when x=0.03,and it could be 101.4K when the sample was irradiated by neutron beam and γ-ray in certain dose.更多还原
