Unexpected observation of spatially separated Kondo scattering and ferromagnetism in Ta alloyed anatase TiO(2) thin films

We report the observation of spatially separated Kondo scattering and ferromagnetism in anatase Ta(0.06)Ti(0.94)O(2) thin films as a function of thickness (10–200 nm). The Kondo behavior observed in thicker films is suppressed on decreasing thickness and vanishes below ~25 nm. In 200 nm film, transp...
