# Anisotropic angle-dependent Andreev reflection at the ferromagnet/superconductor junction on the surface of topological insulators

@article{Salehi2023AnisotropicAA, title={Anisotropic angle-dependent Andreev reflection at the ferromagnet/superconductor junction on the surface of topological insulators}, author={Morteza Salehi}, journal={Physica Scripta}, year={2023}, volume={98} }

We theoretically demonstrate that a ferromagnetic/superconductor junction on the surface of three-dimensional topological insulators (3D TIs) has an anisotropic angle-dependent Andreev reflection when the in-plane magnetization has a component perpendicular to the junction. In the presence of in-plane magnetization, the Dirac cone’s location adjusts in the k-space, whereas its out-of-plane component induces a gap. This movement leads to the anisotropic angle-dependent Andreev reflection and…

It is theoretically shown that a normal/ferromagnetic junction on the surface of 3D TIs bends the propagation direction of Dirac fermions when the magnetization has a component perpendicular to the junction, which leads to a Hall conductance which flows parallel to the interface.

The chiral Majorana mode generated in N/FI/S and S/ FI/S junctions is very sensitively controlled by the direction of the magnetization m in the FI region, and has a phase shift of neither 0 nor pi that can be tuned continuously by the component of m perpendicular to the interface.
