摘要：We report a study of the structural and magnetic
properties, as well as of the heat release, of an
iron/wüstite composite, prepared from iron powder and water
by high energy mechanical milling. We identify that the
produced sample consists of α-Fe nanoparticles embedded in
a wüstite matrix and has high stability in time. Moreover,
we observe that it presents noticeable features, as
exchange bias effect at low temperatures and, when an
alternating magnetic field is applied, its temperature
reaches ∼46 °C in ∼600 s. Thus, the results and the
possibility of tuning the magnetic properties of α-Fe
nanoparticles embedded in a wüstite matrix, through
interface interactions, place this system as a very
attractive candidate for biomedical applications such as
magnetic hyperthermia agent for cancer therapy.
