摘要：
Epitaxial TbMnO3 films have been fabricated on SrTiO3(001) and LaAlO3(001) substrates by pulsed laser deposition (PLD), the structure and surface morphology of the films were characterized by X-ray diffraction with Cu K-alpha radiation and atomic force microscopy. The electrical transport and magnetic properties of the TbMnO3 films and bulk were examined, the resistivity and the forbidden band width E-g change with epitaxial orientation, semiconductor transport properties are found in the films and bulk, the average of the E-g of the films on SrTiO3 and on LaAlO3 is equal to the E-g of the bulk. The two TMO films have different magnetization mode, the magnetization of the film on SrTiO3 have an analogy to that of TbMnO3 single crystal. (c) 2005 Elsevier Ltd. All rights reserved.
