Spin current generator based on topological insulator coupled to ferromagnetic insulators

Spin current generator based on topological insulator coupled to ferromagnetic insulators

We propose a spin current generator based on a topological insulator current-in-plane spin valve, consisting of a 3D topological insulator sandwiched between two ferromagnetic insulator layers. The “on” and “off” states of the spin current can be toggled by switching the magnetization configuration...
