Figure 4: Magnetization per Mn atom versus film thickness.
From: Emergent nanoscale superparamagnetism at oxide interfaces
(a) Saturation magnetization derived from global measurements normalized by the number of Mn atoms in the entire thickness N of the films (green), the theoretically calculated average magnetization per Mn atom taking into account the SPM and the AFM canting contributions (red), and the average magnetization assuming a dead layer of Nc=5 u.c. and 0.85 μB per Mn in the rest of N−Nc live layers (dotted). (b) Saturation magnetization derived from global measurements like in (a) but normalized by the number of Mn atoms in the N−Nc live layers assuming zero magnetization in the Nc dead layers (blue). The dotted line shows magnetization of 3.5 μB per Mn in the live layers as expected in highly doped LMO.
