Influence of microstructural defects on the martensitic transformation and on the magnetic properties of ni-based heusler alloys
(2019-03-14)
The thesis deals with the effect that microstructural defects have on the magneticproperties and martensitic transformation in Ni-Mn-Z (Z = Ga, In, Sn)and Ni-Fe-Ga alloys. For this purpose, along with the standard ...
Magnetoimpedance in Symmetric and Non-Symmetric Nanostructured Multilayers: A Theoretical Study
(MDPI, 2019-04-12)
Intensive studies of the magnetoimpedance (MI) effect in nanostructured multilayers provide a good phenomenological basis and theoretical description for the symmetric case when top and bottom layers of ferromagnet/condu ...
Removal of Tetracycline Pollutants by Adsorption and Magnetic Separation Using Reduced Graphene Oxide Decorated with Alpha-Fe₂O₃ Nanoparticles
(MDPI, 2019-02-26)
Nanocomposites of reduced graphene oxide (RGO) with ferromagnetic alpha-Fe₂O₃ nanoparticles have been prepared in-situ by thermal treatment. The structure and morphology of the hybrid material were studied by X-ray ...
