我们找到了最有前途的粉末材料，应用于热凝治疗肿瘤组织。Y3ΔXGdXFe5O12系粉末材料在1100℃焙烧时的生热能力最大(−T=40~77℃，370 kHz，1.77kA·m−1)。对于FeFe2O4微粒作为这类治疗的候选材料，在相同的磁场下，该ΔT值高于约ΔT=30°C。随着立方单相的形成，颗粒的长大可能会影响到较高的产热。一个意想不到的结果是，Gd3Fe5O12(X=3)在交流磁场中没有生热能力。
We found the most promising powder material for the application of the thermal coagulation therapy for the treatment of cancerous tissues. The maximum heat generation ability (ΔT=40–77°C, 370kHz, 1.77kA·m−1) was obtained for the powder materials by the calcination at 1100°C for the Y3−XGdXFe5O12system. This ΔT value is higher than ca. ΔT=30°C in same magnetic field for fine FeFe2O4particles as the candidate material for this type of therapy. The particle growth with the formation of the cubic single phase might influence to the high heat generation. As an unexpected result, the Gd3Fe5O12(X=3) has no heat generation ability in an AC magnetic field.
