铁氧体薄膜形成用组合物和铁氧体薄膜及其形成方法
摘要：
本发明的课题在于提供一种铁氧体薄膜形成用组合物和利用该组合物的铁氧体薄膜的形成方法及以该方法形成的铁氧体薄膜，所述铁氧体薄膜为用于通过溶胶-凝胶法形成铁氧体薄膜的组合物，其能够形成较薄且均匀的膜厚的铁氧体薄膜，且长期保存稳定性优异。该铁氧体薄膜形成用组合物，其为用于通过溶胶-凝胶法形成NiZn铁氧体、CuZn铁氧体、NiCuZn铁氧体薄膜的组合物，上述组合物通过将金属原料溶解于包含乙腈的溶剂而成，将上述组合物设为100质量%时的乙腈的比例为30～60质量%。
摘要（英）：

To provide a ferrite thin film-forming composition material that is a composition material for forming a ferrite thin film by using the sol-gel method which can form a thin ferrite thin film having a uniform thickness and, furthermore, has excellent long-term storage stability, a method of forming a ferrite thin film using the above composition material, and a ferrite thin film formed by using the above method. A ferrite thin film-forming composition material is a composition material for forming a NiZn ferrite, CuZn ferrite, or NiCuZn ferrite thin film by using a sol-gel method, in which the composition material is formed by dissolving metallic raw materials in a solvent including acetonitrile, and the fraction of acetonitrile is 30 mass% to 60 mass% with respect to 100 mass% of the composition material.
