Abstract

The paper investigate how the structural and magnetic properties and magnetoresistance of the La0.54Ho0.11Sr0.35Mn1- xCoxO3 change with the increase of Co content. Manganites were prepared using a conventional solid-state ceramic route. The phase composition of the samples was monitorized by XRD, at room temperature, data being handled with CellRef and suitable Rietveld programs. All synthesized compounds contain as major phase a manganite (Pbnm (SG 62)). The magnetic and transport properties of the samples were performed by means of a Foner-type magnetometer and four probe method, at 1 T, respectively, Hmax=2 T, between 77 and 400 K..
