Spintronics 0.1.0 Released — Pure Rust Spin Dynamics, Spin Currents, and Topological Materials

The first release of Spintronics: a pure Rust library for simulating spin dynamics, spin-current generation, and spin-charge conversion (ISHE, SSE) in magnetic and topological materials. LLG solvers, magnons, skyrmions, FEM micromagnetics, and WASM — an alternative to slow Python/NumPy scripts and fragile C++/Fortran lab codes.
