The research of the magnetic properties of electron system of low dimensional magnetic nanostructures is presented. Namely we discuss the results of study of multilayered and granular nanomagnets that demonstrate the Giant Magnetic Resistance (GMR) and Giant Magnetic Impedance (GMI) phenomena. The Electron Spin Resonance/Ferromagnetic Resonance (ESR/FMR) technique of millimeter waveband has been applied to define the magnetic ordering in the nanostructures dependent on the interaction between single magnetic granules/particles. The magnetization of saturation for various types of Co‐, Fe‐ and Ni‐nanogranular structures as well as the magnetoresonance response is under discussion. (© 2006 WILEY‐VCH Verlag GmbH & Co.
