FERRITE THIN FILM-FORMING COMPOSITION AND METHOD OF FORMING FERRITE THIN FILM |
| 摘要 |
This ferrite thin film-forming composition is a composition for forming a thin film of NiZn ferrite, CuZn ferrite, or NiCuZn ferrite using a sol-gel method, and the composition includes: metal raw materials; and a solvent containing N-methyl pyrrolidone, wherein a ratio of an amount of N-methyl pyrrolidone to 100 mass % of the total amount of the composition is in a range of 30 to 60 mass %. |

1. A ferrite thin film-forming composition for forming a ferrite thin film having a composition, which is represented by (Ni1-xZnxO)t(Fe2O3), (Cu1-xZnxO)t(Fe2O3)s, or (Ni0.80-yCu0.20ZnyO)t(Fe2O3)s (wherein x satisfies 0<x<1; y satisfies 0<y<0.80; and s and t satisfy 0.95≦s≦1.05 and 0.95≦t≦1.05, respectively, and s and t also satisfy s+t=2), using a sol-gel method, the composition comprising:
metal raw materials; and a solvent containing N-methyl pyrrolidone, wherein a ratio of an amount of N-methyl pyrrolidone to 100 mass % of the total amount of the composition is in a range of 30 to 60 mass %. |
