摘      要：To be able to regulate the anionic oxygen position in ferrites,an original compositing method is developed by introducing a porous p-type phase in the n-type matrix of ferrite spinel semiconductors.A result of this method is the synergetic effect of the enhanced mass and charge transport that impacted the morphology and anionic oxygen position within the MgFe_(2)O_(4) *** hypothesis is that fine tuning of the anionic oxygen position in ferrites allows us to regulate their physicochemical properties significantly,with the implications for diverse *** electron exchange interaction(J)between O-centered and octahedral-occupying iron(Fe)-centered orbitals affected both the electrical and magnetic properties of the matrix significantly,supporting our *** three-dimensional variable range electron hopping is one such effect.
