摘要: In this report, the temperature dependent magnetic properties of graphene oxide (GO) have been studied. The is prepared by modified Hummer's method. formation and structural analysis are carried out using XRD Raman spectroscopy. Fourier transform infrared spectroscopy (FT-IR) used to detect presence various functional groups. magnetization curves as a function applied field at temperatures 10, 50, 150, 250 350 K has accomplished. We observed that ferrimagnetism, paramagnetism in lower along with ferromagnetism diamagnetism higher exist multilayer oxide. transition states GO changing discussed based on average anisotropy energy coupling interactions. wrinkled structure defects due surface groups play significant role shaping magnetism GO. ZFC-FC also analyzed explore system further.
