TLDR
In this paper, the X-ray diffraction study showed that all the thin films annealed at different temperatures were in tetragonal rutile structure of SnO2 and confirmed the presence of Fe and Sn and O in the films.Abstract:
Sn1-xFexO2 (x = 0.07) thin films were prepared on to glass substrates using flash evaporation technique and annealed in air at different temperatures. The X-ray diffraction study showsed that all the thin films annealed at different temperatures were in tetragonal rutile structure of SnO2. The Elemental analysis confirms the presence of Fe and Sn and O in the films. The magnetic measurements were carried out using vibrating sample magnetometer and found that the strength of magnetization decreased with increase of annealing temperature.read more

Synthesis and characterization of ferromagnetic cobalt-doped tin dioxide thin films
TL;DR: The optical band gap absorption edge (E 0 ) of Co-doped SnO 2 thin films initially shows a redshift at low x up to x ǫ = 0.12 and then increases at the higher x, which are attributed to the sp−d exchange interactions and alloying effects as mentioned in this paper.

TL;DR: In this paper, the effect of Fe dopant concentrations on structural, optical, and magnetic properties of the synthesized samples was studied and it was confirmed that the samples at lower dopant concentration were tetragonal in structure whereas the samples prepared at higher dopant condition exhibited orthorhombic SnO and Fe2O3 phases along with tetragonal SnO2 structure.
