测量了RuSr2Eu1.5Ce0.5Cu2O10−δ超导体的磁化率、M-H曲线、磁电阻和热电势。由这些测量值得到了磁转变温度Tmag、超导转变温度Tc、上临界场Hc 2、化学势μ和导电能宽Wσ。磁化率（磁阻）测量结果表明：Tmag = 140 K，Tc = 25 K（33 K），Hc 2（0）> 32 T，μ = 8 meV，Wσ = 58.5meV。这些值进行了比较，与其他超导体，并讨论了由此产生的物理信息。
The magnetic susceptibility, M–H plot, magnetoresistance and thermoelectric power of the RuSr2Eu1.5Ce0.5Cu2O10−δ superconductor are measured. Values of the magnetic transition temperature Tmag, superconductivity transition temperature Tc, upper critical field Hc 2, chemical potential μ and energy width for electric conduction Wσ are obtained from these measurements. It has been found that Tmag = 140 K, Tc = 25 K (33 K) from susceptibility (magnetoresistance) measurements, Hc 2(0)> 32 T, μ = 8 meV and Wσ = 58.5 meV. These values are compared with other ruthenate superconductors, and the resulting physical information is discussed.
