Abstract

As a general objective, we intend to make a systematic study of teh effect of interaction and distribution of grain sizes in the thermal and magnetic properties of core-caste type (core / shell) and Ni-NiO nanoparticles dimers like nanoparticle (MFe2O3-Ag/Au with M: Co, Ni or Mn). The nanoparticles are synthesized via wet chemistry, where a good control size can be obtained. In addition, we intend to study the structural and magnetic properties of manufactured nanoparticles in situ in polymer matrices with physical crosslinking process, such as freezing and thawing (FT ferrogeis) and agents such as crossover glutaraldheyde (GA).
