title: Electrical and magnetic properties of La(0.35)Sr(0.65)Ti(1-x)Fe(x)O(3) thin films.
abstract: We report that the La(0.35)Sr(0.65)Ti(1-x)Fe(x)O(3) system forms a solid solution within the composition range 0≤x≤0.5 and a room temperature magnetic semiconductor phase exists at x = 0.20. This system shows an anomalous Hall effect and is ferromagnetic with a large moment per Fe ion. The results show that the strong La doping provides sufficient carriers to the system to maintain carrier-mediated ferromagnetism for low Fe doping. Furthermore, the presence of ferromagnetism within this phase space raises the possibility that the conduction, and hence the magnetism, could be electronically controlled.
