Compare of sizes end of magnetic moments nanoparticles of a magnetit in a colloid solution and in a powder, prepared by a cemical sedymentation (short message)

The magnetization curves of a powder and of a colloidal solution be received to define a sizes and a magnetic moments of nanoparticles. Size of a powder nanoparticle prove to be equal 2.88 of size a nanoparticle of colloidal solution, and a magnetic moment of a powder nanoparticle prove to be equal 1.44 оf that colloidal solution. That`s why, powder nanoparticle content 2-3 nanoparticles of colloid solution with a nonparallel magnetic moments.
