Abstract
In this talk, we demonstrate the intriguing properties of three distinct materials: Sr2FeMoO6 thin films, tungsten (W)-doped Sr2FeMoO6 thin films, and the conducting interface of LaFeO3 and SrTiO3.
Leveraging pulsed laser deposition (PLD) as a versatile technique, we demonstrate precise control over the stoichiometry of Sr2FeMoO6 thin films, thereby achieving the highest spin-polarization within the system. Additionally, for W-doped Sr2FeMoO6 thin films, we observe fascinating transitions in both conductivity and magnetism, alongside the emergence of a substantial topological Hall effect, indicative of a non-trivial spin-texture arising from intricate ferro-antiferro interactions.
Transitioning from thin films to interfaces, we explore the crystallographic transition occurring at the LaFeO3-SrTiO3 interface, which induces a magnetic transition leading to a remarkable shift from non-spin polarized to spin-polarized conductivity. This novel phenomenon manifests as a room temperature sp...
