Description

Fe-doping (up to 11 mole%) into SrRuO3 (SRO) thin films on SrTiO3 substrates decreased correlation lengths of both surface and interface. It turned out that Fe was doped in the valence state of 3+ without formation of the Fe2O3 phase, which caused orthorhombic distortion. TC values decreased from 145 K to 97 K with increasing Fe concentration (CFe). High magnetic switching fields were observed for all Fe-doped SRO thin films and their strengths showed a linear relationship with CFe. Detail structural characterization using synchrotron X-ray diffraction and X-ray photoemission spectroscopy were used to understand its unique magnetic switching field properties. (orig.)
