Abstract
Maximum solubility of Sn4+ ions in the spin glass Fe2Ti1-xSnxO5 (pseud obrookite) corresponds to x = 0.22(3) at T = 1250 degrees C, and Sn4ions appear to occupy only 4c octahedral sites amongst the 4c and 8f s ites. According to EPR data, the observed spin glass transition temper ature T-g depends on tin concentrations nonmonotonically. The T-g valu es correlate with the measurement times typical of EPR and some other methods. This correlation is well approximated by the empirical Vogel- Fulcher law.
