Structural and magnetic properties of sol-gel Co2xNi0.5−x Zn0.5−xFe2O4 thin films

►The Co content in Co-Ni-Zn films resulted in the grain size ranging from 15 to 32 nm. ►Coercivity increased with Co content independent of grain size. ►Maximum absorption band shifted from 13 to 11 GHz as Co content was increased.
