Nanostructure and magnetic properties of magnesium ferrite thin films deposited on glass substrate by spray pyrolysis

► Thin films of MgFe2O4 are prepared via spray pyrolysis. ► All of the MgFe2O4 films have nanostructure and the special magnetic properties. ► The surface morphology of films in different calcination temperatures is similar. ► The Hc values of our films are independent of the applied field direction. ► The Ms values in the plan and perpendicular directions are not the same.
