Resumen:
-(Sn,Fe)O2 samples were synthesized by mechanical alloying under Ar atmosphere. The powders present two magnetic phases at RT, a paramagnetic and an ordered one. The percentage of ordered phase is almost constant with the composition and may be correlated with oxygen vacancies in the samples. At low temperature a progressive blocking process is observed.
