METHOD TO DETECT MAGNETISATION OF FERRITE SATURATION Russian patent published in 2011 - IPC G01R33/16 

FIELD: measurement equipment.

SUBSTANCE: invention relates to electronic equipment and may find application in research and production of film ferrite materials. Method to detect magnetisation of ferrite saturation includes exposure of sample to permanent magnet field, supply of microwave energy to converters of microwave energy into magnetic static waves, measurement of amplitude-frequency characteristic of delay line or filter, formed by converters with ferrite sample, detection of frequency value f_m on measured amplitude-frequency characteristic, when pole of microwave energy reflection is available, and magnetisation of ferrite saturation M_s is determined using formula: M_s=(2πf_m/µ₀Y)²/H_e-H_e, A/M; where: µ₀ - magnetic constant, equal to 1.26·10^-6, henry/m; Y - gyromagnetic ratio (ratio of electron charge to its mass), equal to 1.76·10¹¹, coulomb/kg; f_m - lower border frequency of surface magnetic static waves, Hz.

EFFECT: detection of film ferrite saturation magnetisation.
