Figure 4

(a) Arrott plot and (inset) M vs. H at 115 K. The lower and upper field limits of the negative slope region are defined as H Arr,1 and H Arr,2. H Arr,1 occurs at fields where M vs. H deviates from linearity and is compared to H C,1. H Arr,2 occurs at the forced ferromagnetic transition. (b) H-T phase diagram defined by the characteristic fields.
