Zusammenfassung: | Present study reports, effect of Cr addition on structural, magnetic properties of CoCrxFe2-xO4 (0.0≤ x ≤ 1.0) ferrites, synthesized by sol-gel auto combustion method. X-ray diffraction (XRD), vibrating sample magnetometer (VSM) were utilized to monitor the modification of structural, magnetic properties, and correlation between them. Scherrer’s grain diameter ranging between 14.7 nm - 26.2 nm. Coercivity (Hc) and anisotropy constant (K1) values respectively ranges between 1249-700 Oe and 20.01×104 to 1.01×104 erg/cc. Best magnetization value of 56.77 Am2/kg was obtained for x = 0.44. Variation of magnetic properties can be understood in terms of Cr-addition induced re-distribution of cations. Coercivity (Hc) dependence with grain size, shows that studied samples lie in the region with overlap between single and multi-domain region. |
