Topology-orientation separability in dual-vortex-driven magnetization
Abstract:
We demonstrate topology-orientation separability in structured-light-driven magnetization in a tight-focusing regime. A nonzero vortex-charge mismatch Δm 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 (β1,β2) rotates the global magnetization orientation without altering the Δm-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.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
