Effect of Cu substitution on Superconductivity in (Ru1-xCux)Sr2(Eu1.34Ce0.66)Cu2Oz System
Description
The effect of Cu substitution on the structural and superconducting properties of the (Ru1-xCux)Sr2(Eu1.34Ce0.66)Cu2Oz system with x = 0, 0.25 and 0.5 prepared under ambient pressure have been investigated. The X-ray diffraction patterns indicated that the Ru ions are replaced by the Cu ions. It is found that the Cu substitution for Ru significantly reduces the ferromagnetic component of field-cooled magnetic susceptibility, but results in a small change in diamagnetic onset transition temperature of zero-field-cooled magnetic susceptibility. In contrast to the RuSr2(Eu1.34Ce0.66)Cu2Oz, bulk Meissner effect is observed in the field-cooled magnetization measurements of the Cu doped samples. The experimental results are discussed in connection with the spontaneous vortex phase interpretation.
