abstract = {Magnetite nanoparticles exhibit magnetic properties that
are size and organization dependent and, for applications
that rely on their magnetic state, they usually have to be
monodisperse. Forming such particles, however, has remained
a challenge. Here, we synthesize 40 nm particles of
magnetite in the presence of polyarginine and show that they
are composed of 10 nm building blocks, yet diffract like
single crystals. We use both bulk magnetic measurements and
magnetic induction maps recorded from individual particles
using off-axis electron holography to show that each 40 nm
particle typically contains a single magnetic domain. The
magnetic state is therefore determined primarily by the size
of the superstructure and not by the sizes of the
constituent sub-units. Our results fundamentally demonstrate
the structure – property relationship in a magnetic
mesoparticle.},
