Mössbauer and magnetic measurements have been made in the perovskite superconductors La1.85Sr0.15Cu1-x57FexO4 for x=0.0025, 0.005, 0.01, 0.05 and 0.10. The superconducting transition temperature is rapidly depressed as x increases, reaching Tc=0 for x≈0.03. Mössbauer data for x=0.05 show behavior below ≈15 K which indicates magnetic ordering. Magnetic susceptibility data give an effective moment of 3-4 μB/Fe atom, and a hand-like susceptibility which increases with x. © 1987.
