Kawakami" ], "categories": [ "cond-mat.mes-hall" ], "abstract": "The transport of spin currents across interfaces is relatively well studied, while the transport properties of orbital currents are just starting to be examined. In Cr/Ni bilayers, the spin-orbit torque (SOT) due to the orbital current generated in the Cr layer is believed to dominate over torques of other origins. In this work, we study SOT in Cr/X/Ni trilayers, where X is an ultra-thin spacer of a different material. Using the SOT as a proxy for the orbital current transferred from the Cr to the Ni layer, we compare Cr/X/Ni results to Pt/X/Ni, the system in which spin current generated in the Pt layer plays a dominant role. We find that across 12 different spacers the apparent interface transparency to the orbital current is comparable or larger than to the spin current.", "revisions": [ { "version": "v1", "updated": "2024-06-04T03:09:56.000Z" } ], "analyses": { "keywords": [ "orbital current", "spin current", "pt layer plays", "apparent interface transparency", "dominant role" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
