A solid solution of vanadium (V)‐doped tin oxide (SnO 2 ) particles of average diameter 2 nm and V content of 19 at.% was prepared at normal pressure and low temperature (100°C) by mixing wet SnO 2 gel SnO 2 · x H 2 O with a boiling solution of vanadium oxide (V 2 O 5 ). Experimental characterizations using X‐ray, electron diffraction, and transmission electron microscope show evidence of a pure single phase. The nanoparticles exhibit a mixed magnetic behavior, namely paramagnetic and ferromagnetic. Their thermal stability is also investigated. At higher temperature, 850°C, some amount of Fe precipitates from the solid solution.
