Report on magnetic, electrical and magnetoresistive properties of the nanoheterostructures

Temperature dependences of the magnetization in zero-field cooling (ZFC) and field-cooling (FC) modes in the temperature range 4.2–300 K and magnetic fields up to 12 T will be investigated. Investigations of the temperature dependences of electrical resistivity will enable the determination of the dominant electron scattering mechanisms in the presence of the dielectric barriers. The measurements of temperature and field dependences of magnetoresistance will allow to determine the nature of the magnetoresistive effect.
