Fig7A.dat contains the data from Figure 7A. The file consists of 4 double columns of temperature (T) in kelvin (K) versus magnetic susceptibility (chi) in metres-cubed per gram (m^3/g) for the four samples: 10 mM Mn phi29 (Cols 1, 2); 15 mM Mn phi29 (Cols 3, 4); 10 mM Mn Bst (Cols 5, 6); 15 mM Mn Bst (Cols 7, 8). 

Fig7B.dat contains the data from the inset to Figure 7B. The file consists of 4 double columns of magnetic field (B) in tesla (T) versus magnetization (M) in Amp metres-squared per gram (Am^2/g) for the four samples: 10 mM Mn phi29 (Cols 1, 2); 15 mM Mn phi29 (Cols 3, 4); 10 mM Mn Bst (Cols 5, 6); 15 mM Mn Bst (Cols 7, 8). 

Fig7C.dat contains the data from Figure 7C. The file consists of two columns of temperature (T) in kelvin (K) versus magnetic susceptibility (chi) in metres-cubed per gram (m^3/g) for the sample 15 mM Co phi29.
