Fecha de publicación: | 14-abr-2022 | Editor: | Royal Society of Chemistry (UK) | Citación: | Journal of Materials Chemistry C 10(15): 5914-5921 (2022) | Resumen: | Spin to charge conversion process in a broad range of temperatures is studied in La0.92MnO3/Pt bilayers prepared by polymer-assisted deposition (PAD). It is shown that an excellent LMO/Pt interface can be obtained in spite of using ex situ deposition of the Pt layer. The values obtained for the effective spin-mixing conductance, g↑↓eff = 0.76 × 1015 cm−2, suggest that significant spin transport across the LMO/Pt interface could be achieved. Spin pumping experiments generate a transversal voltage signal VISHE, due to spin to charge conversion via inverse spin Hall effect, that has been detected down to about 100 K with values of the spin-Hall angle, θSH, of about 2.5%, slightly decreasing on reducing temperature in the analyzed temperature range. These results indicate that LMO is a promising perovskite building block for all-oxide multifunctional high-frequency spintronics devices and that PAD technique provides oxide epitaxial thin films of good quality adequate for spintronic applications. | Versión del editor: | http://dx.doi.org/10.1039/d2tc00048b | URI: | http://hdl.handle.net/10261/269730 | DOI: | 10.1039/d2tc00048b | ISSN: | 2050-7526 |
