FIG. 1.

Results of the M vs H curve analysis for the MnFe2O4 nanoparticles. Corresponding particle size distribution function, f(r), is shown in the inset.

FIG. 2.

Temperature dependence of magnetization decay for the MnFe2O4 nanoparticles cooled under a magnetic field of 100 G. The histogram is the anisotropy energy barrier distribution fA (T) deduced from Eq. (3).

Image of FIG. 3.
FIG. 3.

Temperature dependence of the effective magnetic anisotropy constant K(T) for the MnFe2O4 nanoparticles. The inset shows the variation of TB as a function of r obtained programmatically from the analysis of Eq. (4).
