%X The preparation of <i>¦Ã</i>-Fe<sub>2</sub>O<sub>3</sub>/Gd<sub>2</sub>O<sub>3</sub> nanocomposite for possible use in magnetic hyperthermia application was done by
ball milling technique. The nanocom<span>posite
was characterized by X-ray diffraction (XRD) and vibrati</span>ng sam<span>ple magnetometer (VSM). The heating efficiency
and the effect of milling</span> time (5 h and 30 h) on the structural and
magnetic properties of the nanocomposite were reported. XRD analysis confirms
the formation of the nanocomposite, while magnetization measurements show that
the milled sample present hy<span>steresis with
low coercivity and remanence. The specific absorption rate</span> (SAR) under
an alternating magnetic field is investigated as a function of the milling
time. A mean heating efficiency of 68 W/g and 28.7 W/g are obtained for 5 h and
30 h milling times respectively at 332 kHz and 170 Oe. The results showed that
the obtained nanocomposite for 5 h milling time is a promising candidate for
magnetic hyperthermia due to his properties which show an interesting magnetic
behavior and high specific absorption rate.
