Magnetic materials require multiscale modelling across electronic, atomistic, micromagnetic and device levels. MaMMoS provides a unified Python framework that links these steps and avoids manual data translation. Based on ground-state magnetic parameters from DFT databases, it computes their temperature dependence using atomistic spin-dynamics, and passes them directly to micromagnetic solvers for modelling hysteresis and switching. Common analysis tools (e.g., coercivity, remanence) are included, and benchmarking and optimisation are possible. Planned extensions include machine-learning based modules to replace simulations with faster, approximate estimates. We present the current prototype to attract early adopters and invite community feedback.
