In Mn3O4, the crystal structure, dislocation density, particle size and spin of the electrons plays crucial role in modulating its magnetic properties. Present study investigates impact of Biofield treatment on physical and atomic properties of Mn3O4. X-ray diffraction revealed the significant effect of biofield on lattice parameter, unit cell volume, molecular weight, crystallite sizes and densities of treated Mn3O4. XRD analysis confirmed that crystallinity was enhanced and dislocation density was effectively reduced by 80%. FTIR spectroscopic analysis revealed that Mn-O bond strength was significantly altered by biofield treatment. Electronic spin resonance analysis showed higher g-factor of electron in treated Mn3O4 as compared to control, along with altered spin-spin atomic interaction of Mn with other mixed valance states. Additionally, ESR study affirmed higher magnetization behaviour of the treated Mn3O4. The results demonstrated that treated Mn3O4 ceramic could be used as an excellent material for fabrication of novel magnetic data storage devices.
