The size effect of the dielectric properties and the barrier height was investigated in the ferroelectric solid solution Ba<Subscript> x </Subscript>Sr<Subscript>1−x </Subscript>TiO<Subscript>3</Subscript> system. The decrease of the grain size causes the suppression of the ferroelectricity, and the increase of the relaxation frequency. Barrier heights increase...</subscript></subscript></subscript>

In this study, FeNi<Subscript>3</Subscript>/Al<Subscript>2</Subscript>O<Subscript>3</Subs cript> core-shell nanocomposites, where individual FeNi<Subscript>3</Subscript> nanoparticles were coated with a thin layer of alumina, were fabricated by a modified sol-gel method. Several physical characterizations were performed on the samples of FeNi<Subscript>3</Subscript>/Al<Subscript>2</Subscript>O<Subscript>3</Subs cript> nanocomposites with different...<//subs></subscript></subscript></subscript></subscript><//subs></subscript></subscript></subscript>

We have demonstrated a simple and universal morphology-controlled growth of 2D ordered Fe/SiO<Subscript>2</Subscript> magnetic nanodots array, which was based on 2D colloidal monolayer template composed of polystyrene (PS) spheres and one-step sol-gel spin-coating technique. The Fe/SiO<Subscript>2</Subscript> nanodots have a well-ordered...</subscript></subscript>
