摘要：

Magnetic hyperthermia experiments were carried out using a biphasic gel of La1-xSrxMnO3(LSMO) and gamma-Al-0.07 Fe1.93O3 with an AC magnetic field of amplitude 88mT and a frequency of 108 kHz. Specific absorption rate (SAR) increases with the increased ratio of Al-substituted maghemite. The T-max 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. & 2009 Elsevier B.V. All rights reserved.
