Abstract
We report here our Raman studies on Fe3-xZnxO4(x=0,0.015,0.03) across the Verwey transition in the temperature range 20-300 K. The changes in Raman spectra as a function of doping show that the changes are gradual for samples with higher Zn doping. Allen's formula has been used to estimate the strength of electron-phonon interaction from the observed lineshape parameters. These estimates show that there is strong electron-phonon coupling in this system and is highest for the T2g3 mode in comparison to A1g and T2g2 modes.
