Abstract
We investigate the structural and magnetic properties of Fe2TiO5 nanopowders prepared by ball-milling and post annealing. From the structural analysis, we observe the crystalline signature of the pseudobrookite phase. Moreover, by exploring distinct aspects of the magnetic behavior, we find fingerprints of the longitudinal spin freezing, with cluster spin glass transition taking place at 56 K, and of the presence of the Dzyaloshinskii-Moriya interaction in the system. Further, we observe antiferromagnetic features for the nanopowder at 300 K, and hysteresis loop with an abrupt change in magnetization characterizing the ferromagnetic behavior at 4 K. The results place the employed route as a simple, low-cost candidate to the production of nanopowders, especially Pseudobrookite.
