A Study Of Copper And Aluminum Incorporated Chromium Oxide Core-Shell Magnetic Nanoparticles, Tamzid Ibn Minhaj
MSU Graduate Theses
The structural and magnetic properties of copper (Cu) and aluminum (Al) -incorporated chromium oxide (α-Cr2O3, i.e., chromia) inverted core-shell nanoparticles (CSNs) were investigated. The objectives of this study were to determine the role of the substituting (for chromium, Cr) element and of Cu concentration on governing the magnetic properties of the CSNs. For synthesis of the CSNs, α-Cr2O3 nanoparticles were first grown using microwave assisted synthesis whereupon a hydrothermal nanophase epitaxy (HNE) method was used to incorporate Cu or Al in the chromia-based shell of the nanoparticles. The morphology, structure and size characteristics …
