Research ArticleOpen accessEffect of Magnetic Field on the Formation of Spin-polaron in Mn-Zn FerritesH. M.El SayedThe effect of magnetic field on the transport properties of Mn-Zn ferrite was studied. It was found that, the resistivity has an inverse relation with the applied magnetic field. This was attributed to the reduction of the scattering between the charge carriers and the disordered spins. Also, it was found that, the activation energy in the paramagnetic region is strongly … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2007 · 6,507 accessesView PDFCite
