Critical Analysis on the Structural and Magnetic Properties of Bulk and Nanocrystalline Cu-Fe-O
Figure 14
Room temperature hysteresis loops of bulk and nanocrystalline (50 hour refluxed, annealed at 900°/2h) Cu0.95Fe0.05O showing five-fold increase in coercivity. Inset shows the increase in value with increasing “Fe” concentration in nanocrystalline samples.
