Characteristics of magnetic powder in a high-frequency magnetic field. FIG. 3. Heating principle of thermosensitive magnetic powder coated with a metal. We define the Curie point as T C and the temperature of the powder as T . FIG. 4. Temperature characteristics of the magnetic powder: (a) Temperature profile and (b) temperature rise per minute. FIG. 5. Characteristics of thermosensitive magnetic powder coated with Ag paste in a high-frequency magnetic field. FIG. 6. Temperature rise per minute of the powder as a function of the product of ( f B ) 2 .

N2 - Soft heating, where thermosensitive magnetic materials inserted into the tumor as a heater produce heat in a high-frequency magnetic field, has been proposed as one method. Although the heater needs to be implanted in the tumor tissue, soft heating has advantages including easy retreatment, localized tumor heating, and a low degree of invasiveness. We created thermosensitive magnetic powder coated with Ag paste as a heater. As a result, this powder produced a greater amount of heat due to losses through hysteresis and inductive current than the magnetic powder alone, and we could also control the temperature of the heater by using the Curie point.
