With new ferromagnetic implant with low curie point (Ni 70.4%, Cu 29.6%), temperature elevation and distribution in phantom, animal and tumor implanted in rabit were studied. Elevation of temperature both in phantom and muscle in rabit was satisfactory regarding the strength of magnetic field and time reguired to be plateau level. At the curie temperature of 50°C, center of the 4 implants separeted 1.5 cm earch showed 45°C, but in the muscle of rabbit, it reached 42°C. The difference was interpreted by the cooling effect of blood flow in the muscle. Temperature elevation in VX-2 tumor in rabbit was also demonstrated.
