Annealing effects on the ferromagnetism of Ce0.97Co0.03O2-δ compounds

Modification of Ce valence states by Sm/Sr co-doping of CeO 2 nanoparticles for improved magneto-electrochemical properties

“…The development of the spintronic technology is now a very active area of research. Moreover, it exhibits a cubic structure with a lattice parameter (a = 0.54113 nm) close to that of Si, offering the possibility that CeO 2 devices might be integrated with conventional silicon-based electronic circuits [3][4][5][6][7][8][9][10].…”

“…CeO 2 doped with TMs such as Fe, Co, Ni, Mn and Cu or REs such as Sm, Nd, Pr and Gd have been found to exhibit RT-FM which has been explained by a V O mediated F-center exchange (FCE) mechanism [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In addition to their advantageous magnetic properties, improved electrical, optical and catalytic properties have been found in alkaline earth (AE) and REdoped CeO 2 materials.…”
