چکیده انگلیسی
Ferrogels are composite materials widely introduced in the area of biomedical engineering as magnetic field sensitive transformers. These biomimetic materials can be prepared by incorporating monodomain magnetic nanoparticles into chemically crosslinked hydrogels. The properties of a biomimetic ferrogels taken for the study unlike that of the biological prototype might be set up by the synthesis and can be thoroughly controlled in a physical experiment. In this work we developed a giant magnetoimpedance sensor with a multilayered FeNi/Ti-based sensitive element adapted for ferrogel studies. Ferrogels were synthesized by radical polymerization of acrylamide in a stable aqueous suspension of γ-Fe2O3 MNPs fabricated by laser target evaporation. The magnetoimpedance measurements in initial state and in the presence of ferrogels with concentrations of nanoparticles from 0 to 2.4 wt% in a frequency range of 1-300 MHz allowed a precise characterization of the stray fields of the nanoparticles present in the ferrogel.
