Title: Magnetic and transport properties of cobalt doped La₀.₇Sr₀.₃MnO₃

The magnetic and transport properties of La₀.₇Sr₀.₃Mn{sub 1–x}CoxO₃ (0≤x≤1) samples were systematically studied. A magnetic phase diagram was constructed according to the observed results. At the two ends (x ≤ 0.3 and x>0.9), the samples exhibit the conventional ferromagnetism with the metallic conducting behavior, which can be interpreted in terms of the double exchange coupling between Mn (Co) ions. As for the intermediate Co-doping region (0.3
