A simple ammonia fueled combustion route was used to synthesize a series of nanocrystalline porous CoFexAl2-xO4 spinel samples with different Fe concentration (0.00 ≤ x ≤ 2.00) at 400 ◦C. The structural, morphological, and textural properties of the synthesized powders were analyzed by using XRD, FT-IR, FESEM, TEM, SAED, and N2-physisorption techniques. The electrical and magnetic properties of the spinels ... Read more
