Evolution of magnetic and magnetoresistive properties of sputtered NiFe/Cu/Co/Cu nanostructures under ageing and annealing
Magnetic and magnetoresistive properties of sputtered Ni₈₀Fe₂₀(4-6 nm)/Cu(2-10 nm)/Co(2 nm)/Cu(2 nm) nanostructures have been studied after room temperature ageing and thermal annealing at 75-150°C. Magnetic properties of Co/Cu bilayer and NlFe/Cu one were investigated. The transformations of field...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Magnetic and magnetoresistive properties of sputtered Ni₈₀Fe₂₀(4-6 nm)/Cu(2-10 nm)/Co(2 nm)/Cu(2 nm) nanostructures have been studied after room temperature ageing and thermal annealing at 75-150°C. Magnetic properties of Co/Cu bilayer and NlFe/Cu one were investigated. The transformations of field dependences of magnetoresistance, and the nanostructure hysteresis loops have been considered. The evolution of characteristics in the nanostructure as a whole is supposed to be due to changes in magnetic properties of the upper Co/Cu layer, namely, to the magnetic anisotropy deterioration and the appearance of separate single-domain and superparamagnetic particles. |
