New results on Magnetic Properties of Tin-Ferrite Nanoparticles

Abstract

This paper presents new physical properties of nanocrystalline SnFe 2 O 4 ferrites, synthesized by co-precipitation method. Magnetization measurement indicates superparamagnetic behavior; the blocking temperature is about 300 K. We performed X-ray diffraction, infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Energy Dispersive Spectroscopy (EDS), UV-visible measurement, superconducting quantum interference device (SQUID) and zero-field-cooled (ZFC)/field-cooled (FC) measurements. TEM images show the high crystallinity and grain size of ferrite nanocrystals. The refinement result showed that the type of the cationic distribution over the tetrahedral and octahedral sites in the nanocrystalline lattice is a partially inverse spinel. The obtained UV-vis data were used to calculate the energy band gap (3.82 eV) of nanocrystalline SnFe 2 O 4 . On the other hand the magnetic properties of the samples; saturation magnetization (M s ) and coercive field (H c ) were determined using a superconducting quantum interference device (SQUID).

A cost-effective, stable, magnetically recyclable photocatalyst of ultra-high organic pollutant degradation efficiency: SnFe2O4 nanocrystals from a carrier solvent assisted interfacial reaction process

“…SnFe 2 O 4 is a paramagnetic iron-containing inverse spinel binary oxide with both of its constituent metal elements, Sn and Fe, being relatively earth-abundant. 28 It received little research attention in the past, but is proven to be an outstanding catalyst for Fentonlike processes in this work. It is a semiconductor with a direct bandgap of 2.53 eV, capable of absorbing visible light, and functions through both chemical and photochemical catalyzations.…”

Assessment of SnFe2O4 Nanoparticles for Potential Application in Theranostics: Synthesis, Characterization, In Vitro, and In Vivo Toxicity

“…XRD pattern ( Figure 3 ) of fabricated SnFe 2 O 4 NPs represents a series of narrow and broad diffraction signals characteristic for pure and good-quality nanoparticles. In accordance to JCPDS database, the single-phase spinel-related structure was identified (code 22-1086) [ 11 ]. The mean size of crystallites was determined by using Scherrer equation and was found in the range of 15 to 50 nm.…”

“…A facile and cost-effective hydrothermal approach was followed to synthesize high-quality nano-sized particles [ 11 ]. Following this typical procedure, SnFe 2 O 4 NPs were synthesized with specific ratios of precursors, i.e., tin chloride, ferric chloride and sodium hydroxide.…”
