Annealing effect on the structural and magnetic properties of the CuAl 0.6 Cr 0.2 Fe 1.2 O 4 nano-ferrites

Structural phase transition of as-synthesized Sr–Mn nanoferrites by annealing temperature

“…Co-Cr-, Co-Mn-. , Mn-Ni-, Mn-Znand Cu-Al-Cr-nanoferrite samples were annealed at different temperatures and characterized by using different techniques [4][5][6][7][8][9]. The obtained results proved that the sample properties were varied with annealing temperature range.…”

Annealing effect on structural phase transition of as-synthesized Mg0.1Sr0.1Mn0.8Fe2O4 nanoparticles

“…Due to the dependence of ε on R, its variation reflects the thermal expansion coefficient of the samples when they were annealed, which is assigned to the change of spacing within and/or between the nanoparticles. The increase of ε proves growth of the crystal lattice as T increases [11,26,27].…”

Structural phase transformations of as-synthesized Cu-nanoferrites by annealing process

“…The obtained negative values of ε prove compressive strain [20,26,27], The obtained values of ε are plotted against T as displayed in Fig. 5.…”
