What are the Key Components of Spintronic Devices?
The critical components of spintronic devices include:
Ferromagnetic materials: These materials, such as iron, cobalt, and nickel, are used to inject and detect spin-polarized electrons. Spin valves: Structures consisting of alternating ferromagnetic and non-magnetic layers that control the electron spin alignment, crucial for data storage. Magnetic tunnel junctions (MTJs): Devices where two ferromagnetic layers are separated by a thin insulating barrier, used in magnetic random-access memory (MRAM). Spin transistors: Transistors that utilize electron spin to control current flow, promising for high-speed and low-power applications.
