  In this work we elaborated and characterized nanocomposite thin films using a
preselected multiferroic matrix Bi$_{0.9}$Gd$_{0.1}$Fe$_{0.9}$Mn$_{0.1}$O$_3$
(BGFMO) in the aim to enhance their basic ferroelectric and magnetic
properties. The local ferroelectric character of these nanocomposites thin
films was investigated by piezoresponse force microscopy (PFM). Switching
behavior for ferroelectric domains was probed by locally manipulating domains.
The magnetic investigation showed that the incorporation of transition metal
elements in the BGFMO matrix brings out interesting increase in the macroscopic
magnetisation at room temperature. Moreover, a spin glass type behavior is
observed in M(T) curves for the studied thin films.
