Abstract

The effect of Mn substitution for Cu in mixed-valence Mn-doped La1.85−4∕3xSr0.15+4∕3xCu1−xMnxO4 has been investigated by electric resistivity, dc magnetic susceptibility, and electron spin resonance measurements. Robust superconductivity with x up to 0.2 coexisting with ferromagnetism was observed surprisingly. Percolative superconductivity is suggested based on the discussion about the origin of the ferromagnetism.
