Out-of-Plane and In-Plane Magnetization Behavior of Dipolar Interacting FeNi Nanoislands around the Percolation Threshold

Figure 5

A schematic illustration of the temperature-dependent ZFC and FC magnetization response (and of the associated difference, shown by a solid black line) for FM NPs. (a) For SPM phase of weakly interacting NPs. (b) For SPM phase of weakly interacting NPs, coexisting with SFM phase of strongly interacting NPs. Here, red star symbols correspond to the additional hysteretic-like SFM contribution. (c) Modeling the in-plane negative response (shown in Figure 4(c)) above the NP’s system percolation threshold. Here, the FC curve is obtained by subtraction of the SFM contribution, .
