attention as a candidate to produce logic and
memory devices. The use of growth techniques
such as pulsed laser deposition allowed the
production of thin films with high quality con-
trol. Multiferroic thin film heterostructures of
BiFeO and LaBiFeO were grown to evaluate
3 3
and test their electrical and magnetic proper-
ties. The multiferroic project was developed at
the University of California - Berkeley covered
by the Everton Bonturim doctoral project and
his supervisor Professor R. Ramesh, looking
to improve the state-of-the-art in devices
technologies through the pure and applied
nanoscience (Figure. 69).
