Abstract

Nanocrystalline films were directly prepared by spray deposition of a preformed polyol-based Ni_0.8Zn_0.2Fe₂O₄ sol on a moderately heated glass substrate. The microstructural and magnetic properties of these films are investigated by X-ray diffraction, scanning electron microscopy and magnetic measurements on a Super Quanducting Interference Devices magnetometer. They are compared with those of nanoparticles precipitated from the sol, and with those of film subsequently annealed in air at 400 °C. The films and the powder exhibit superparamagnetic behaviour with a blocking temperature which increases from the powder to the as-produced film to the annealed film, in agreement with increasing stress and/or crystal size. They are ferrimagnetic at low temperature with a hysteresis feature strongly dependent on the synthesis conditions.The stresses induced in the film upon deposition undoubtedly correlate with a large grain boundaries volume which contributes to the H_c, the coercitive field, increase and M_sat, the saturation magnetization, decrease.

 sol on a moderately heated glass substrate. The microstructural and magnetic properties of these films are investigated by X-ray diffraction, scanning electron microscopy and magnetic measurements on a Super Quanducting Interference Devices magnetometer. They are compared with those of nanoparticles precipitated from the sol, and with those of film subsequently annealed in air at 400 °C. The films and the powder exhibit superparamagnetic behaviour with a blocking temperature which increases from the powder to the as-produced film to the annealed film, in agreement with increasing stress and/or crystal size. They are ferrimagnetic at low temperature with a hysteresis feature strongly dependent on the synthesis conditions.The stresses induced in the film upon deposition undoubtedly correlate with a large grain boundaries volume which contributes to the H<sub>c</sub>
, the coercitive field, increase and M<sub>sat</sub>
, the saturation magnetization, decrease.</s0>
