The study investigates the ferromagnetism observed at and above room temperature in pulsed laser deposited epitaxial films of Co-doped Ti-based oxide perovskite (La0.5Sr0.5TiO3-δ). It is found that the films range from being opaque metallic to transparent semiconducting depending on the oxygen pressure during growth. The dependence of the magnetic and transport properties on y and γ suggests a strong role of carrier density, dynamics and materials related issues.
