METHOD OF DETERMINING MAGNETIC AND STRUCTURAL CHARACTERISTICS OF NANOMETER SPATIALY-ORDERED SYSTEMS Russian patent published in 2009 - IPC G01N23/20 B82B1/00 

FIELD: physics, measurements.

SUBSTANCE: proposed invention is intended for defining the magnetic and structural characteristics of nanometre spatially-ordered systems. The proposed method consists in that, on defining the said characteristics, an external magnetic field is applied, at the point the specimen interacts with neutron beam, either parallel with or perpendicular to the neutron beam propagation direction. The external magnetic field magnitude is varied from zero to maximum and visa versa. The dependence of neutron scatter intensity upon the angle of scatter in external magnetic field is measured with the help of position-sensitive detector. The total and differential dependencies of the opposite-spin-orientation neutron scatter angular intensities upon external magnetic field magnitude are determined for parallel and perpendicular components relative to scatter intensity without external magnetic field. Now, the hysteresis shape of the aforesaid dependencies is used to determine the specimen magnetic properties and reversal magnetisation character.

EFFECT: simultaneously gained magnetic and structural characteristics of spatially-ordered nanostructures.
