FIELD: measurement equipment.
SUBSTANCE: implementation of a method for determining the magnetization of the substance pattern of regular geometric shape is placed in a magnetic field measured by induction in the sample at the point where the normal of the sample surface induction line H tension at the point where the line of tension parallel to the surface of the sample, and determining the magnetization of the sample according to the formula M=B/μo-H. The values of the magnetization M1 and M2 are measured for two different 180 degrees from the direction of external magnetic field orientations of the sample. Next, calculate the magnetization Zeeman formula Ms=(M1+M2)/2 and the magnetization Neel formula Mn=(M1-M2)/2. Neel formula Mn=(M1-M2)/2.
EFFECT: ability to control the magnetizations Zeeman and Neel ferromagnetic nanoparticles in powders used for the production of magnetic fluids.
