摘要：

We have studied the magnetic properties of fine particles of iron and iron carbide nested in carbon cages (nanocapsules), which were synthesized by arc discharge of carbon rods. It is clarified by Mossbauer spectroscopy and thermomagnetic (M-T) curve that these particles consist of alpha-Fe, gamma-Fe and Fe3C. Their coercive force is larger than that of bulk alpha-iron, being ascribed to the small particle size observed by high-resolution (HR) transmission electron microscopy (TEM).
