A comparative study of the magnetization in transition metal ion doped CeO2, TiO2 and SnO2 nanoparticles

Tunable fluorescence and magnetic properties of ceria- organic core- shell hollow structures

“…In the past two decades, due to the rise of spintronics and magnetic oxides, a considerable number of researchers have been involved in the study of defect engineering in ceria nanostructures for the regulation of magnetic properties. Three main approaches have been followed on that aspect : (1) Doping; various elements, including magnetic transition metals and nonmagnetic rare earth elements have been doped into ceria [8,9,10,11]. (2) Reduction; it has been found that the oxygen vacancies can be introduced into CeO 2 through post reduction process.…”

Magnetic Properties of Rare Earth Doped SnO2, TiO2 and CeO2 Nanoparticles

“…It is known that the materials for spintronics must have a large magnetization as well as a Curie temperature above room temperature. Therefore it seems that for the application in the spintronics it is more appropriate the doping of oxide NPs with transition metal than with RE ions because M decreases with increasing of the most RE dopant ions whereas by the most TM doping ions the magnetization M increases . It must be noted that our scheme − the connection between lattice parameters, exchange interaction constants and magnetization − is also applicably by the investigation of the magnetic properties of TM doped CeO 2 , TiO 2 , SnO 2 NP oxides as well as TM doped ZnO NPs …”
