Fabrication of thin films is crucial in the study of fundamental properties of matter and designs of devices. In
this work, multiferroic dysprosium manganites DyMnO₃ thin films were grown epitaxially on SrTiO₃ (001) and
yttrium stabilized zirconia (111) [YSZ (111)] substrates by pulsed laser deposition technique. The fabricated
films showed perfectly orthorhombic crystallization on SrTiO₃ (001) and hexagonal crystallization on YSZ (111)
substrates. At low temperatures, the magnetic measurements revealed three magnetic transitions at 10 K, 21 K
and 43 K for orthorhombic DyMnO3 film, 7 K, 38 K and 58 K for hexagonal DyMnO₃ film, respectively. The
results are consistent with those observed in bulk materials, corresponding to magnetic ordering of the Dy³⁺ ion
spins, antiferromagnetic transitions and spin reorientation respectively. This work provides a convenient
method to manipulate the film structure by choosing suitable substrates, and it can be used in the study of magnetic
properties of multiferroic manganites and related device fabrication.
