Magnetic, Pseudocapacitive, and HO-Electrosensing Properties of Self-Assembled Superparamagnetic CoZnFeO with Enhanced Saturation Magnetization.

The present work explores the structural, microstructural, optical, magnetic, and hyperfine properties of CoZnFeO microspheres, which have been synthesized by a novel template-free solvothermal method. Powder X-ray diffraction, electron microscopic, and Fourier transform infrared spectroscopic techniques were employed to thoroughly investigate the structural and microstructural properties of CoZnFeO microspheres. The results revealed that the microspheres (average diameter ∼121 nm) have been formed by self-assembly of nanoparticles with an average particle size of ∼12 nm.
