Abstract
We investigate the Andreev reflection properties of a two-dimensional p-wave Altermagnet-superconductor junction. The Altermagnet materials have special spin texture in the absence of spin-orbit interaction and create a new class in the category of magnetic materials alongside ferromagnet, anti-ferromagnet, etc. Here, we show that Andreev reflection is sensitive to the propagation direction of incoming fermions and breaks the mirror symmetry with respect to perpendicular direction when the strength-vector of Altermagnet has a component parallel to the junction’s interface. Due to mirror symmetry breaking a transverse spin current flows parallel to the junction. The creation of spin current in the absence of long-range magnetization of ferromagnets and spin-orbit interaction is crucial in spintronics.
