Advanced Science, EarlyView.A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.
