We report on the growth and functional characterizations of epitaxial thin films of the
multiferroic Y Mn O 3⁠. We show that using Pt as a seed layer on Sr Ti O 3 (111) substrates,
epitaxial Y Mn O 3 films (0001) textured are obtained. An atomic force microscope has been
used to polarize electric domains revealing the ferroelectric nature of the film. When a
Permalloy layer is grown on top of the Y Mn O 3 (0001) film, clear indications of exchange
bias and enhanced coercivity are observed at low temperature. The observation of …
