      Oxide-Melamine Mixture.

AB  - Nitrogen-doped carbon nanomaterial (NDCNM) was synthesized by grinding a mixture 
      of graphene oxide and melamine in a planetary mill with both balls and milling 
      chamber of zirconium dioxide. In the electron spin resonance spectrum of NDCNM, a 
      broad signal with g = 2.08 was observed in addition to a narrow signal at g = 
      2.0034. In the study using a vibrating-sample magnetometer, the synthesized 
      material is presumably a ferromagnet with a coercive force of 100 Oe. The 
      specific magnetization at 10,000 Oe is approximately 0.020 and 0.055 emu/g at 
      room temperature and liquid nitrogen temperature, respectively.
