Title: Gd-doped BaSnO 3: A transparent conducting oxide with localized magnetic moments

Abstract

We have synthesized transparent, conducting, paramagnetic stannate thin films via rare-earth doping of BaSnO 3. Gd 3+(4f 7) substitution on the Ba 2+ site results in optical transparency in the visible regime, low resistivities, and high electron mobilities, along with a significant magnetic moment. Pulsed laser deposition was used to stabilize epitaxial Ba 0.96Gd 0.04SnO 3 thin films on (001) SrTiO 3 substrates, and compared with Ba 0.96La 0.04SnO 3 and undoped BaSnO 3 thin films. Gd as well as La doping schemes result in electron mobilities at room temperature that exceed those of conventional complex oxides, with values as high as 60 cm 2/V·s (n = 2.5 × 10 20cm -3) and 30 cm 2/V·s (n = 1 × 10 20cm -3) for La and Gd doping, respectively. The resistivity shows little temperature dependence across a broad temperature range, indicating that in both types of films the transport is not dominated by phonon scattering. Gd-doped BaSnO 3 films have a strong magnetic moment of ~7 μB/Gd ion. Such an optically transparent conductor with localized magnetic moments may unlock opportunities for multifunctional devices in the design of next-generation displays and photovoltaics.
