Thin films of Bi1.05La0.05FeO3 (BLFO) were deposited on a CaRuO3 buffering layer on SrTiO3 using pulsed laser deposition, followed by in situ sputtering of a Pt thin layer on the surface of BLFO. The magnetoresistance effect was observed at the interface of the Pt/BLFO bilayer, indicating the possibility of manipulating spin-orbit coupling at the interface of a single-phase multiferroic and a heavy metal.
Thin films of Bi1.05La0.05FeO3 (BLFO) have been deposited on a CaRuO3 buffering layer on SrTiO3 using pulsed laser deposition. Then, a Pt thin layer was in situ sputtered on the surface of BLFO. The crystallization characteristic and surface morphology of the BLFO layer were checked. Spin transporting behaviors of the Pt/BLFO structure were investigated at room temperature. Interestingly, a magnetoresistance effect was observed at the interface of the Pt/BLFO bilayer. The spin mixing conductance at the interface between BLFO and Pt was estimated after a corrections of Pt thickness. This implies that the manipulation of spin-orbit coupling is possible at the interface of a single-phase multiferroic (e.g., BLFO) and a heavy metal (e.g., Pt).
