High-field Mössbauer study of the randomly canted Li-Fe-Ti system

In-field Mossbauer studies have been performed on the Li0.5(1+t)Fe2.5−1.5t,Ti t ,O4 system with 1.10 ≤t≤ 1.40. The disordered magnetic properties depend strongly on the chemical disorder and local order induced by thermal treatments. The results are in agreement with low- and high-field magnetization measurements. Locally canted states are observed, with the degree of magnetic disorder depending on the composition and (or) the local chemical disorder.
