Abstract

We have prepared the carbon-based ferromagnets by pyrolytic method under high magnetic field and investigated their crystal structure and magnetic properties. The crystal structure was measured by the synchrotron X-ray diffraction experiment. The diffraction peak of a diamond was observed for the ferromagnetic samples. Thus, the carbon-based ferromagnet can be attributed to the ferromagnetic ordering of radical spins generated by defects in the diamond structure. And, the diffraction peak of a diamond of the ferromagnetic samples increased with the applied magnetic field in sample preparation. Therefore, the magnetic field may help to form a three dimensional ferromagnetic structure in the carbon-based ferromagnet. The highest magnetization was 3.0 emu/g at 300 K for the sample prepared under magnetic field at 6 T.
