Figure 8
Calculated magnetic response of MnFe2O4 nanoparticles with an applied AC field with kA/m and kHz. (a) Steady magnetization curves, and (b) mean orientation of the easy axis of the nanoparticles, . In the inset in (a), the ellipsoid shows a nanoparticle, and the broken line, open and closed arrows indicate the directions of the easy axis, magnetic moment of the particle, and the AC magnetic field, respectively. The variation of easy axis orientations is illustrated in the sketches in (b).
