Magnetic Properties and AC Losses in AFe₂O₄ (A = Mn, Co, Ni, Zn) Nanoparticles Synthesized from Nonaqueous Solution

Figure 4

The magnetization versus magnetic field dependences for the NPs of zinc, manganese, cobalt, and nickel spinel ferrites. The magnetization curves were obtained at 10 K. Inset shows the same dependences in the region of low fields.
