We present a comparative study on the ferroic properties of complex oxides nano-structured in nano particles 3D, needles 2D, and films 1D. Nanovaractors of barium titanate BaTiO3 and barium strontium titanate BST thin films have been successfully fabricated through advanced E-beam lithography and inductively coupled plasma ICP dry etch. Additionally, the superparaelectric SPE phenomena of ferroelectric materials have been discussed. Finally, we have explored the solutions to discover the superparaelectric phase through temperature dependence and electrical property tests.
