Sol–Gel Route for the Synthesis of CoFe2–xErxO4 Nanocrystalline Ferrites and the Investigation of Structural and Magnetic Properties for Magnetic Device Applications

“…The calculated H k values are summarized in Table . It is seen that the H k values increased for doped samples, which resulted in an increase in coercivity. , …”

“…The magnetocrystalline anisotropy constant, K , largely depends on the saturation magnetization value. 5 Also, the anisotropy field H k for a cubic crystal along with the easy direction [1 0 0] can be obtained using the relation 39 , 40 …”

“…It is seen that the H k values increased for doped samples, which resulted in an increase in coercivity. 39,40 The net magnetic moment of CoFe 2 O 4 is attributed to the difference in magnetic moments of the cations from the octahedral site and the tetrahedral site. 19 Figure 11b shows the net magnetic moment of CoFe 2 O 4 as a function of Er content.…”

“…Moreover, other structural factors like crystallite sizes and porosities also play a vital role in the enhancement of the ferromagnetic behaviour of the ferrite samples. 29,30 The sizes of crystallites (d 114 ) in all studied samples were estimated from the diffraction peak at (114), which represents the major phase (hexagonal) and calculation was performed by the Debye-Scherrer formula 31 as expressed by the following equation:…”
