Title:
MAGNETIC FILM AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2019212735
Kind Code:
A
Abstract:
To provide a magnetic film having high magnetic permeability.SOLUTION: A magnetic film contains a binder, and ferrite magnetic nanoparticles having an average particle diameter of 100 to 500 nm and ferrite magnetic microparticles having an average particle diameter of 1 to 100 μm dispersed in the binder, and the distribution constant m assuming to follow Rosin-Rammler distribution function in which the particle size distribution (mass basis) of the ferrite magnetic nanoparticles is represented by the formula: F(Dp)=1-exp(-(Dp/De))) (where F represents an integrated mass ratio under the sieve, and Dp represents the particle diameter, De represents the particle size characteristic number, and m represents the distribution constant] is in a range of 1.6 to 2.3.SELECTED DRAWING: Figure 1
