Topology-orientation separability in dual-vortex-driven magnetization

We demonstrate topology-orientation separability in structured-light-driven magnetization in a tight-focusing regime. A nonzero vortex-charge mismatch Δ m produces an azimuthal phase beating that generates a twisted optical spin density through nonparaxial transverse-longitudinal coupling, thereby inducing three-dimensional magnetization textures via the inverse Faraday effect. Crucially, the tilt-angle pair ( β 1 , β 2 ) rotates the global magnetization orientation without altering the Δ m −defined twisted topology. These two orthogonal control channels, not achievable within a single-beam configuration, enable deterministic steering of three-dimensional magnetization textures and scalable twisted magnetization lattices. This minimal two-parameter framework provides a compact route toward multidimensional opto-magnetic control.
