Abstract

The invention relates to the field of electronic material and device and discloses a method for preparing a cobalt ferrite magnetic thick film. The method comprises the following steps that the cobalt ferrite is dispersed in a solvent to prepare a suspension with uniform concentration; subsequently, the thick film is prepared by electrophoretic deposition under a constant electric field condition. The prepared cobalt ferrite magnetic thick film has high coercive field and magnetic saturation intensity, can be applied to the preparation of thick film capacitors and phase shifters and has the advantages of simple equipment, low cost, quick film-forming process and easily controlled components.

Description

technical field

[0001] The invention belongs to the field of electronic materials and devices, and in particular relates to a method for preparing a cobalt ferrite magnetic thick film. Background technique

[0002] Among the spinel-structured ferrites, spinel nano-ferrites are widely used in information storage systems, medical diagnostic technology, magnetic fluid technology, magneto-caloric and magnetic-refrigerated due to their good magnetic properties. .

[0003] Cobalt Ferrite CoFe 2 o 4 It has high magnetocrystalline anisotropy, coercive field, saturation magnetization and stable chemical properties, so CoFe can be used 2 o 4 These properties make functional devices. At present, the research on magnetoelectric materials mainly focuses on CoFe 2 o 4 and NiFe 2 o 4 superior. Among them, cobalt ferrite (CoFe 2 o 4 , abbreviated as CFO) is a magnetic material with the advantages of high magnetocrystalline anisotropy, coercive field and saturation magnetization,...
