Preparation and Characterization of Polyimide-Cobalt Ferrite Nanocomposite

Mazuera D., Cedeño Y., Perales-Perez O., Singh S.P., University of Puerto Rico-Mayagüez, PR

Synthesized 20 nm cobalt ferrite single crystals, which exhibited a coercivity of 2.9kOe at room-temperature, were dispersed in precursor polyamic acid at different volume fractions and cured at 300oC to develop the polyimide matrix. Polyamic [...]

Optimization of Magnetic Properties in Cobalt Ferrite Nanocrystals

Cedeño Y., Perales-Perez O., Roman F., Singhal R., Tomar M.S., University of Puerto Rico, Mayaguez Campus, PR

Among the various ferrite materials for magnetic recording applications, cobalt ferrite (CoFe2O4) possesses excellent chemical stability and good mechanical hardness. Furthermore, the large positive first order crystalline anisotropy constant has made this ferrite a promising [...]
