Figure 7From: Role of vanadium ions, oxygen vacancies, and interstitial zinc in room temperature ferromagnetism on ZnO-V2O5 nanoparticlesVariation 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.Back to article page
