Abstract	:	Magneto-electronic phase separation refers to the presence of multiple magneticand electronic phases within a material that is chemically homogeneous. It is verycommon in oxides and has been related to their most exciting properties such assuperconductivity and colossal magnetoresistance (CMR). In this work, phase separationin perovskite Lal.,Sr,Co03 was investigated comprehensively by conventionalmagnetometry and electrical measurements as well as Small Angle Neutron Scattering(SANS), Nuclear Magnetic Resonance (NMR), and Transmission Electronic Microscopy(TEM). All the work leads to a consistent picture based on short range ferromagneticordering and intrinsic magnetic phase separation. When the doping is less than 18 , thedoped cobaltites separate into ferromagnetic (FM) metallic clusters embedded in the non-FM insulating matrix. With increasing x,.
