Cation distribution in nanocrystalline Al3+ and Cr3+ co-substituted CoFe2O4

Perpendicular magnetic anisotropy in 70nm CoFe2O4 thin films fabricated on SiO2/Si(100) by the sol–gel method

“…[1][2][3][4][5][6][7][8]. The modification of magnetic and dielectric properties of CFO can be realized through substitution [9][10][11], fabrication of monodispersed purified hollow ferrite spheres [12] and growth of CFO films on different substrates using various techniques such as sputtering, molecular beam epitaxy, pulsed laser deposition and sol-gel method [3,4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Considering practical applications in magnetic recording, the sol-gel method is an attractive alternative to other deposition methods due to its advantages such as lower annealing temperature, easier composition control, non-vacuum process and easier fabrication of large area thin films [21,23].…”

Effect Of Al3 Inclusion on Characterization Exploration, Magnetic and Anti Cancer Properties of Cobalt Ferrite Nanoparticles Synthesised by Co Precipitation Process

“…This result is assisted by earlier procedure conclusion wherein the CoFe 2 O 4 NPs displayed toxicity just at high concentrations [52,53]. As stated in the existing Trojan horse theory for metal NPs, metal ions dropped with the NPs can insert the fibroblast cells and create cytotoxicity [54]. The live, necrotic and apoptotic cells are put together after the incubation period, which could result in the danger of dose-dependent CoFe2O4 NPs and could be limited by proper dose control of NPs.…”

Effect of graphene on the microstructure, mechanical properties, and wear behavior of plasma‐sprayed Al2O3–Cr2O3 coating

“…Therefore, the diffraction peak intensity of Cr 2 O 3 in the coatings decreases noticeably compared with that of Cr 2 O 3 in the feedstocks. The radius of Cr 3+ (.63 Å) is larger than that of Al 3+ (.51 Å) 32 . Thus, the solution of Cr 3+ in α‐Al 2 O 3 crystal lattice would lead to the shift of diffraction peak of Al 2 O 3 .…”
