MAGNET STRUCURESCOPY METHOD Russian patent published in 2007 - IPC G01R33/12 

FIELD: magnetic measurements.

SUBSTANCE: structurescopy method can be used for investigation of physical properties of materials as well as of their structure and composition. Method is based upon detection of crystalline nano-phase in amorphous array of nano-crystalline material; for the purpose parameters of Barkhauzen' jumps are used. Method concludes in re-magnetization of checked material by variable magnetic field, in registration of Barkhauzen's jumps, on measurement of their parameters and in judgment on structure of material on base of characteristics of the parameters. Checked material is re-magnetized locally by variable magnetic field with frequency of 10 kHz. Oscillogram of envelope of flow of Barkhauzen's jumps is taken as measured parameter received from primary converter. Shape of oscillogram is used to judge on presence of crystalline nano-phase in amorphous array of nano-crystalline material. According to preferable version of manufacture, local re-magnetization is carried out by attached primary converter.

EFFECT: improved reliability of measurement of parameters.
