When a spin wave current ${\\bf j}_m$ flows in a system with a homogeneous magnetization {\\bf m}, this interaction produces an effective field-like torque on the form ${\\bf T}_{\\rm FL}\\propto{\\bf m}\\times({\\bf z}\\times{\\bf j}_m)$ as well as a damping-like torque, ${\\bf T}_{\\rm DL}\\propto{\\bf m}\\times[({\\bf z}\\times{\\bf j}_m)\\times{\\bf m}]$ in the presence of spin-wave relaxation (${\\bf z}$ is normal to the interface). These torques mediated by the mag"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.0883","kind":"arxiv","version":2},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
