Low-dimensional magnetic architectures including wires and thin films are key enablers of prospective ultrafast and energy efficient memory, logic and sensor devices relying on spin-orbitronic and magnonic concepts. Curvilinear magnetism emerged as a novel approach in material science, which allows tailoring of the fundamental anisotropic and chiral responses relying on the geometrical curvature of magnetic architectures. Much attention is dedicated to magnetic wires of Möbius, helical or DNA-like double helical shapes, which act as prototypical objects for the exploration of the fundamentals of curvilinear magnetism. Although there is a bulk number of original publications covering fabrication, characterization and theory of magnetic wires, there is no comprehensive review of the theoretical framework of how to describe these architectures. Here, we summarize theoretical activities on the topic of curvilinear magnetic wires and narrow nanoribbons, providing a systematic review of the emergent interactions and novel physical effects caused by the curvature. We discuss prospective research directions of curvilinear spintronics and spin-orbitronics, outline the fundamental framework for curvilinear magnonics and introduce mechanically flexible curvilinear architectures for soft robotics.
