Abstract:
In our current study, we have investigated the impact of manganese (Mn) doping on the
structural, magnetic properties, and hydroelectric cell properties of cobalt ferrite with chemical
formula [Co1-xMnxFe2O4, x=0.00, 0.125]. The solid-state approach has been utilized to synthesize
the material. XRD measurements revealed the formation of an inverse spinel cubic structure with
the space group Fd-3m. FTIR spectra hold a shift in the octahedral and tetrahedral bands with the
increase in Mn content in cobalt ferrites. The subsequent rise in ferroelectric behavior has been
observed with the net maximum saturation polarization of 1.08μC/cm2. The variation in the
permittivity values has been also studied with the increase in Mn content for dry as well as wet
hydroelectric cells. The impedance measurements helped us understand the contribution of
grains/grain boundaries in the prepared ferrites. The enhanced value of magnetization has been
noticed from 48.258 emu/g to 73.089 emu/g upon doping of Mn ions in cobalt ferrite spinel
structure lattice. The Mn doped CFO exhibited enhanced performance in hydroelectric cells which
demonstrates the great ionic diffusion mechanism with the incorporation of Mn ions. The obtained
output makes Mn doped CFO a suitable material for studying microelectronic and hydroelectric
cell applications. The purpose of this study is to enhance both ferroelectric as well as ferromagnetic
behavior along with the improved value of current in hydroelectric cells.
