Spectroscopic analysis for electric and magnetic properties of manganese doped cobalt nanoferrite

Structural characteristics, cation distribution, and elastic properties of Cr3+ substituted stoichiometric and non-stoichiometric cobalt ferrites

“…2,3 In particular, cobalt ferrite (COF) has got enormous importance both in technological as well as biomedical applications. [3][4][5][6][7][8][9][10][11][12][13] Intensive studies on COF have been carried out with varying doping and/or substituting the divalent or trivalent cations and synthesizing them by different methods. 3,14,15 In order to conrm the crystallinity and the phase of the synthesized materials, Rietveld renement has been signicantly used on the X-ray diffraction (XRD) data of the samples.…”

“…3,14,15 In order to conrm the crystallinity and the phase of the synthesized materials, Rietveld renement has been signicantly used on the X-ray diffraction (XRD) data of the samples. 1,[9][10][11]16 Amri et al 1 have calculated the theoretical lattice parameters along with hopping lengths, oxygen positional parameters, cationcation and cation-anion bond lengths of Ni-Zn-Al ferrite. Kumar et al 14 have reported on the estimation of the lattice parameters by using Nelson-Riley (N-R) function, intrinsic strain and crystallite size by using Williamson-Hall (W-H) method.…”

Influence of Mg substitution on structural, magnetic and electrical properties of Zn-Cu ferrites

“…The reason behind the ferrite being more interesting is their high resistivity (about 15 times higher than the pure iron), which is extremely demanding for high-frequency applications [2]. Also, ferrites are the most important due to the lower price, higher frequency applicability, higher heat resistance, and higher corrosion resistance [3]. Ferrites are typically categorized into two kinds: one is hard ferrites and another one soft ferrites [4][5][6].…”

Photocurrent response loss of dye sensitized solar cells owing to top surface nanograss growth and bundling of anodic TiO2 nanotubes

“…Based on Fig. 9(a) , the values for f max were obtained respectively 2.81, 2.51, 1.25, 1.58, 1.77 Hz for anodized photoanoodes for five different times of 20, 60, 120, 240 and 360 min and the electron lifetime was estimated using the following equation [ 55 ]. where τ is value for electron lifetime, f max is maximum frequency of second semi-circle in nyquist plot.…”
