Hole-doped manganite La0.7Ca0.3MnO3 materials has been extensively studied because of its colossal magnetoresistance (CMR) characteristic in a magnetic field. Recently, a new member of CMR family La0.7Ce0.3MnO3 , an electron-doped manganite, raises a new wave of attention for possible application of p-n junctions.
Single Phase La0.7Ce0.3Mn3 films were usually grown by the pulse laser deposition (PLD) technique with a relatively narrow growth window around 755¢J¡Ó5¢J. In this study, we use a RF sputtering technique to grow La0.7Ce0.3Mn3 epitaxial films, which has not been tried yet. Films are grown on SrTiO3, MgO and LaAlO3 substrates. The best film have the metal-insulator transition temperature (TP) 304K and the curie temperature (TC) 310K, which are higher than that of grown by PLD method
