  1. aHc: coercivity;
  2. bTf: the freezing temperature above which the NPs gradually shift from clusters-glass (CG) like state to the ferromagnetic (FM) state;
  3. cTm: the merging temperature for zero-field-cooling curves (MZFC(T)) and field-cooling curves (MFC(T)), indicating that the NPs are in the same FM state for ZFC and FC processes above that temperature;
  4. dData from X Shen, et al., RSC Advances 4, 34179(2014).
