Abstract
A series of Zn1−x Ni x Fe2O4 nano ferrite (with x = 0 , 0.2, 0.4, 0.6, 0.8, 1) compositions were synthesized using the hydrothermal technique. The powder samples were characterized by XRD, VSM, and FTIR. The X-ray analysis showed that the samples had a single phase spinel cubic structure. The lattice constant decreased with increasing Ni content from 8.373 to 8.279 Å. The FTIR spectra of the samples in the range 200–5000 cm−1 were reported. The hysteresis loops of the samples were performed at room temperature, the coercivity (H c), saturation magnetization (M s), experimental magnetic moment (μ exp) and retentivity (M r) were determined. The magnetic entropy change was calculated from measurements of M(H,T) where H is the magnetic field and T is the temperature. The maximum value of entropy change (ΔS) increased as the applied field increased, which makes these material candidates for magnetocaloric effect.
