The temperature dependent magnetization (ZFC) at for the undoped, Ti-doped, C-doped, and C–Ti-doped samples.
behavior at for the undoped, Ti-doped, C-doped, and C–Ti-doped samples. For the sake of comparison, the results of nanocarbon-doped (Ref. 9) and CNT-doped are plotted in the figure. Inset: Magnetization hysteresis loops at for undoped, Ti-doped, and C–Ti-doped samples.
