| Outline of Final Research Achievements |
Garnet type Y3Fe5O12 ferrite powder having high heat generation ability in AC magnetic field was investigated to apply the thermal coagulation therapy for cancerous tissue.
The heat generation ability was significantly improved by reverse co-precipitation method with lower pH value, the highest heat generation (ΔT=183℃) was obtained at pH=7.10 sample. The hysteresis loss value was also increased with decrease the pH value, it suggest that the heat generations of Y3Fe5O12 powder in AC magnetic field might be caused by hysteresis loss. A physical milling method using bead milling was very effective for preparing the nano sized Y3Fe5O12 powder having high heat generation ability in AC magnetic field.
