Abstract

Topological semimetal materials have attracted a great deal of attention due to their intrinsic strong spin-orbit coupling, which leads to large charge-to-spin conversion efficiency and novel spin transport behaviors. In this work, we have observed a bilinear magnetoelectric resistance (BMER) of up to 0.0034 nm²A⁻¹Oe⁻¹ in a single layer of sputtered semimetal Pt₃Sn at room temperature. Being different from previous works, the value of BMER in sputtered Pt₃Sn does not change out-of-plane due to the polycrystalline nature of the Pt₃Sn layer. The observation of BMER provides strong evidence of the existence of spin-momentum locking in the sputtered polycrystalline Pt₃Sn. By adding an adjacent CoFeB magnetic layer, the BMER value of this bilayer system is doubled compared to the single Pt₃Sn layer. This work broadens the material system in BMER study, which paves the way for the characterization of topological states and applications for spin memory and logic devices.
