Abstract

We report the existence of a Griffiths-like phase over a wide range of x due to the formation of nanosize ferromagnetic clusters in La _0.6Sr_0.4Mn_1-xCo_xO₃, the solid solution of ferromagnetic La_0.6Sr_0.4MnO₃ and La_0.6Sr_0.4CoO₃, from the magnetization measurements. In the studied compound, this phase arises due to the quenching of randomly distributed Co-O-Mn antiferromagnetic bonds in the ferromagnetic background. In contrary to the divalent alkaline-earth-doped manganites, the Griffiths-like phase in La_0.6Sr_0.4Mn_1-xCo _xO₃ can exist entirely in the metallic state above T _C (for x < 0.10). Based on the present study, a magnetoelectronic phase diagram is drawn.
