Laser induced spin injection to [GeTe/Sb2Te3] superlattice through a TbFeCo film

A [GeTe/Sb2Te3] superlattice is known as a topological insulator and it shows magnetic responses such as magneto-optical effect although it does not contain any magnetic element. We reported the superlattice has topologically protected spin diffusion length more than 100 μm at room temperature. In t...
