Magnetic properties of nanostructured CoxFe3−xO4 (0<x<0.2) thin films obtained by a low-temperature soft solution processing method

Highly ordered transition metal ferrite nanotube arrays synthesized by template-assisted liquid phase deposition

“…This behavior was furthermore confirmed by the measurement of the hysteresis loops at 5 K (Fig. 6(c) [42][43][44] Similar to the Zn-ferrite nanotube arrays, the Ni-ferrite nanotubes are superparamagnetic at room temperature, with a blocking temperature of 256 K (ZFC/FC data not shown).The hysteresis loops of the Ni 0.66 Fe 2.34 O 4 nanotubes measured at room temperature and 5 K with the magnetic field applied parallel to the long axis of the nanotubes are presented in Fig. 7 (a) and (b).…”

“…Recently, Hsu and coworkers extended this approach to the synthesis of multicomponent oxide nanotubes, such as perovskite titanates ABO 3 (A ¼ Ba and Pb), 40,41 whereas our research group developed a LPD-based synthetic methodology for the fabrication of highly uniform transition metal ferrite films, 42,43 as well as magnetoelectric bilayered structures, respectively.…”

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].…”

Mechanochemical synthesis and characterization of nanodimensional iron–cobalt spinel oxides

“…Among spinel ferrites, cobalt ferrite CoFe 2 O 4 is especially interesting because of the high cubic magnetocrystalline anisotropy, high coercivity, and moderate saturation magnetization. The properties of these ferrites are highly sensitive to the concentration of divalent metal ions, to substituting other metallic ions for the divalent ions and to the crystallite size [18][19][20][21]. Many synthesis strategies for preparing nanosized cobalt ferrite have been reported [21][22][23][24][25].…”
