In this work, we explore conformational effect on spin selective electron transmission considering a magnetic Möbius strip, a one-sided nonorientable surface. Unlike a regular magnetic cylinder, having a two-sided surface, a magnetic MS exhibits several peculiar phenomena in the presence of magnetic scattering of itinerant electrons with local magnetic moments at different lattice sites of the strip. Employing a tight-binding framework to describe the system, we use Green’s function formalism to investigate spin-dependent transport phenomena. Vertical hopping plays an important role, and for suitable hopping strength, we can have a high degree of spin polarization (
) for a wide bias window, even when the Fermi energy is set at zero. The effects of ring size, system temperature, interface sensitivity, and spin-dependent scattering factor are critically investigated. A comparative analysis with a regular magnetic cylinder is also given, to reveal the impact of the topology.
