フェライト粒子、樹脂組成物及び樹脂フィルム

Japanese Patent JP6547229

B2

An object of the present invention is to provide ferrite particles having a high saturation magnetisation, and being excellent in the dispersibility in a resin, a solvent or a resin composition, a resin composition including the ferrite particles, and a resin film composed of the resin composition. The ferrite particles are a single crystalline body having an average particle size of 1 to 2000 nm, and Mn-based ferrite particles having a spherical shape, and have a saturation magnetisation of 45 to 95 Am 2 /kg. The resin composition includes the ferrite particles as a filler. The resin film is composed of the resin composition.
