Figure 4
Angular dependence of S and Siso. The curves were measured at 65 K at 2 T and 3 T for nanocomposite C (open) and nanocomposite D (closed), belonging to nanocomposites I and nanocomposites II in Fig. 3, respectively. The solid lines represent the isotropic contribution Siso(θ), obtained from the scaling Siso(Heff(θ)) as shown in the inset. The inset shows S(θ) as a function of Heff for nanocomposite D at 65 K from 0.1 T until 9 T with γeff = 2.5. The black solid line corresponds to the collapse of Siso (Heff).
