It was demonstrated that the new method employing a coaxial arc plasma gun is a new promising candidate for the forming single-digit nanometer diamond particles easily.We have succeeded the fabrication of the vacuum chamber specialized for powder preparation. The yield rate was approximately 0.4 mg / min is 40 times the previous one. Cr-doped nanodiamond powder exhibited diamond 111 diffraction rings in the electron diffraction patterns and the existence of diamond grains was confirmed from dark-field TEM images. The SR-XRD patterns also exhibited peaks due to diamond. Diamond exists in this powder is verified sp3 component from SR-PES spectra. SR-PES The crystalline size was less than 10 nm. Results of XAFS and SQUID measurements show this Cr-doped nanodiamond powder is magnetic material.
