Abstract :
Multifunctional nature of the Fe-Ti-oxides makes them attractive candidates for novel applications in which their coupled semiconductor, magnetic, dielectric and optical properties can be exploited. In particular, they appear to be good candidates for the emerging technologies such as spintronics, magneto-electronics, and radhard electronics. In this paper we deal mostly with pseudobrookite (Fe2 TiO5), both pure and Mn-substituted variety. Materials processing, structural, magnetic and semiconducting properties have been discussed in-depth. The temperature and magnetic field dependence on the non-liner I-V characteristics are established opening the possibilities for fabricating magnetically switched devices
