Résumé en anglais

Magnetic hyperthermia experiments were carried out using a biphasic gel of La1−xSrxMnO3(LSMO) and γ-Al0.07 Fe1.93O3 with an AC magnetic field of amplitude 88 mT and a frequency of 108 kHz. Specific absorption rate (SAR) increases with the increased ratio of Al-substituted maghemite. The Tmax value for the gels prepared by the mixture of LSMO and Al-substituted maghemite can be adjusted to suit therapeutic temperature. The time required to reach optimum temperature decreased with the increased ratio of later. Such biphasic gel could be very useful for magnetic hyperthermia with in vivo control of temperature.< Réduire
