Transverse Relaxation of a Nuclear Spin System in Bulk and Nanostructured Magnetically Ordered Materials

In the work a comparative study of relaxation processes of the nuclear spin system, described by the characteristic time T2, in bulk and nanostructured materials with magnetic order was carried out. Experimental results obtained by observation of the nuclear magnetic resonance (NMR) signal of 57Fe nuclei, recorded by the spin echo method in lithium-zinc ferrite and in nanostructured magnetite (used as a starting material for the manufacture of magnetic liquids) are presented. The requirements for radiospectroscopic equipment that must be met in the NMR investigations of magnetic nanostructures are discussed.
