Evolution of the Morphology and Magnetic Properties of Flaky FeSiAl/MFe₂O₄ (M = Mn, Co, Ni, Cu, Zn) Composites.

ABSTRACT: Nanosized spinel ferrites MFe₂O₄ (M = Mn, Co, Ni, Cu, Zn)-coated flaky FeSiAl alloy composites were synthesized successfully. Nano-ferrites preferentially grow into nanoplatelets due to induced or restricted growth on the flaky surface of FeSiAl. With annealing temperature increasing, the ferrites' nanosheets thicken gradually and then grow into irregular particles. The annealing temperature not only affects the nanosized morphology and coating but also the magnetic properties of flaky FeSiAl composites. The saturation magnetization of CuFe₂O₄- or NiFe₂O₄-coated FeSiAl is approximate 69 emu/g, where the value of MnFe₂O₄-, CoFe₂O₄- and ZnFe₂O₄-coated FeSiAl sho
