摘要：

In this work we explore how a two-stranded magnetic ladder with vanishing net magnetization can be utilized to generate polarized spin current from a completely unpolarized one. Considering three different types (A-, C-and G-type) of antiferromagnetic ladders within a tight-binding framework, we make a comparative study to find the best suitable ladder for spin filtration. Our analysis can be implemented to design efficient spintronic devices with the help of antiferromagnetic materials, circumventing the use of conventional ferromagnetic systems.
