Abstract

57Fe Mössbauer experiments have been performed on the Li0.5+0.5t Fe2.5−1.5t Ti t O4 ferrite system (t=0, 0.5, 0.8, 1.0) without and in external magnetic fields up to 6 T at 4.2 K and above. The samples up tot=0.8 exhibit collinear ferrimagnetic order and an iron distribution over the A and B sites according to the formula of Blasse. The sample LiFeTiO4 exhibits spin canting. In contrast to other compounds, the canting angle increases with increasing applied field for both A and B sites. The iron distribution ratio differs from the expected value of 1.0.
