Structure and magnetic properties of SnFe2O4 nanoparticles

Mössbauer and D.C. magnetization studies of (CuFe2O4)1−x (SnO2) x (x = 0 and 5 wt.%) nanocomposites

“…Appearance of the paramagnetic doublet may be related to the Sn 4+ ions substitution of Fe 3+ ion neighbors leading to paramagnetic state of iron. Similar paramagnetic doublets were observed in Mössbauer spectra of milled (NiFe 2 O 4 ) 0.3 (SnO 2 ) 0.7 [12] and SnFe 2 O 4 nanoparticles (internal region) [13].…”

Hyperfine interactions in (CuFe2O4)1 − x (SnO2) x (x = 0, 1, 5, 10 and 20 wt.%) nanocomposites studied by Mössbauer spectroscopy

“…Mössbauer parameters of copper ferrite samples (T = 295 K) This doublet is similar to paramagnetic doublets in Mössbauer spectra of magnetically isolated Fe 3+ ions in Al 3+ substituted Li 0.5 Fe 2.5 O 4 [14], SnFe 2 O 4[15] and NiFe 2 O 4 -SnO 2 nanocomposite[16]. From theTable 1the δ values for the 57 Fe nuclei in B-site increases with increasing concentration of SnO 2 up to x = 10 wt.% while the δ values for the 57 Fe in Asite remain the same.…”

Free‐standing and flexible nano‐ZnO/PVDF composite thin films: impedance spectroscopic studies

“…[30] It also has good electrical and optical properties enabling it to be used in a variety of applications such as photoconductors, [31,32] sensors, [33,34] and solar cells. [35,36] The need for flexible electronics devices that can bend, expand, cover irregular surfaces, and be deposited for large-area applications with low-cost manufacturing [37,38] is on hot anvil. Thus, synthesis of composite ZnO/PVDF free-standing flexible films has gathered momentum in recent times.…”
