Fig. 10From: Raman Submicron Spatial Mapping of Individual Mn-doped ZnO NanorodsMFM measurements. MFM images of upright standing ZnO:Mn (Mn15%) NRs measured by MFM tip with opposite polarity of apex, north (N) or south (S) (a–d). Arrow in b shows 2d bottom layer. e Represents diametric profiles of magnetic field gradients (shift of MFM tip oscillation frequency) over top of NRs collected by north (curve 1) and south (curve 2) magnetized MFM tip apexBack to article page
