Magnetic and structural studies of magnetite at the Verwey transition

Studies of the Verwey transition in zinc doped magnetite (Fe 3− x Zn x O 4, x = 0, 0.0097, 0.011, 0.036) by simultaneous ac magnetic susceptibility ( χ) and electric resistance measurements are presented. The temperature hysteresis of the Verwey transition increases from 0.03 K for stoichiometric ma...

Description
Summary:Studies of the Verwey transition in zinc doped magnetite (Fe 3− x Zn x O 4, x = 0, 0.0097, 0.011, 0.036) by simultaneous ac magnetic susceptibility ( χ) and electric resistance measurements are presented. The temperature hysteresis of the Verwey transition increases from 0.03 K for stoichiometric magnetite to 0.5 K for Zn doped samples, despite the continuous character of the transition. The results of introductory observations of structural changes are also presented.
