抄録(英) Mn_<1-x>Zn_xFe_2O_4 thin films with various Zn content, 300nm in thickness, were synthesized on glass substrates at 90℃ without a heat treatment directly by electroless plating in aqueous solution. With XRD, SEM, VSM, the crystallographic structure, morphology of the films and the macroscopic magnetic properties were characterized. The Mn-Zn ferrite films have a single phase spinel structure and well-crystallized columnar grains grow perpendicularly to the substrate. The changes of the H_c is not consistent with that of the bulk materials. As the Zn content in the films increases, the coercivity decreases firstly, and then increases. At x=0.5, the minimum value of H_c is 3.7kA/m and the value of M_s is 419.6kA/m. The hyperfine magnetic fields, cation occupation and the distribution of the magnetic moments in film plane were studied by the conversion electron Mossbauer spectroscopy (CEMS).
