Description

The structural changes and superconductivity of La1.85-2xSr2x+0.15Cu1-xRuxO4 (I) and La1.85Sr0.15Cu1-xRuxO4 (II) systems have been investigated. It was observed that the Ru doping strongly suppresses Tc. The critical contents xc for Tc disappearances are respectively 0.0225 and 0.019 for the (I) and (II) systems. It was found that in all La1.85Sr0.15Cu1-xMxO4 systems investigated (M = Ru, Li, V, Sn, Al, Ga, Co, Fe, Mn, Mg, Ni and Zn), the structure parameter c/a ratios decrease with increasing doping content x, which is a common characteristic. The mechanisms for Tc suppression in the La1.85Sr0.15CuO4 system are summarized and discussed briefly
