Multiferroic DyFeO(3) thin films deposited on (001) Nb-doped SrTiO(3) (NSTO) substrates are prepared by pulsed laser deposition. We demonstrate the epitaxial deposition of DyFeO(3) thin films on the substrates with the DyFeO(3)(001)//NSTO(001) out-of-plane and DyFeO(3)[100]//NSTO[110] in-plane epitaxial relationship. In addition, the weak ferromagnetism and significant magnetodielectric coupling effect at low temperature are revealed. It is indicated that the DyFeO(3) thin films have very different properties from the DyFeO(3) single crystals in term of multiferroicity. (C) 2010 Elsevier B.V. All rights reserved.
