The monovalent (Ag1+)- and divalent (Sr2+)-doped LaMnO3 thin film samples were synthesized. The transport properties and magnetic behavior of the thin film were studied for wide-range colossal magnetoresistance. The film orientation and microstructure were studied using high-resolution X-ray diffraction and atomic force microscope. The electrical transport behavior of thin films is evaluated at 0 and 5 T magnetic field. The temperature dependence of magnetization with applied field of 5000 Oe was measured. The typical hysteresis curves of both the films Sr- and Ag-doped system are plotted.
