This work presents a comprehensive theoretical and system-level analysis of magnetronic computing as a potential post-CMOS paradigm. The manuscript synthesizes advances from spintronics, magnonics, and topological magnetism to outline a unified framework for information processing based on collective spin excitations and topologically protected magnetic textures. The study focuses on voltage-controlled magnon transistors, skyrmion-based logic elements, and non-volatile magnetic memory concepts, with performance estimates derived from analytical modeling, numerical simulations, and extrapolation of experimentally reported material and device parameters available in the published literature. No new fabrication processes or experimental measurements are reported. Key topics include magnon propagation and dispersion, skyrmion dynamics and stability, spin–orbit coupling effects, thermodynamic limits of magnetic switching, and hybrid integration strategies with CMOS, photonic, and superconducting platforms. The manuscript also discusses materials challenges, scalability constraints, and prospective solutions based on emerging two-dimensional magnets and synthetic antiferromagnets. This document is intended to serve as a conceptual reference and forward-looking roadmap for researchers and engineers working on beyond-CMOS computing technologies, energy-efficient hardware, and spin-based information processing.
