Figure 3From: The effects of surface spin on magnetic properties of weak magnetic ZnLa0.02Fe1.98O4 nanoparticlesThe dependence of magnetization on magnetic field. The magnetization (M) dependence on the applied magnetic field (H) (-2 T < H < +2 T), vizM(H) loops of all undiluted samples UD700 (a), UD800 (b), UD900 (c), and UD1000 (d) measured at room temperature. The inset of (a) shows the magnified plot of loop in the low H region.Back to article page
