Fig. 5. Magnetic nanocluster properties.

Fig. 5

(A) Magnetic moment versus temperature under zero field–cooled (ZFC) (black) and field-cooled (red) conditions. The peak in the zero field–cooled curve gives a measure of the energy required to reorient the magnetic clusters. (B) Magnetic moment versus applied magnetic field at 70 K; data are in blue circles, and Langevin fit to the data are shown as a red line. The Langevin fit gives an estimated magnetic cluster density and moment of 2 × 104 Mn clusters/μm2 and 2000 μB, respectively.
