Figure 7.

Variation of saturation magnetization depending on milling time. The maximum for our synthesis parameters was found around 1 h. The inset shows how the TT increased the magnetic moment for samples milled for 8 h. Probably, long-time milling contributes to reduce intrinsic VO on ZnO, thus reducing the defects that mediate ferromagnetic order.
