Novel architectures of magnetic materials
Magnetic
heterogeneous
systems
whose
properties
are
defined
on
a
nanometer

become
one
of
the
most
promising
directions
in
materials
science.
Recent

Combination
of
self–assembly
techniques
with
the
use
of

in
an
effort
to
manipulate
the
local

of
the
nanoparticles
and produce well defined large-scale arrays of magnetic nanoentities.
