A layered magnetic thin film refers to a specific type of material composed of multiple layers of magnetic substances, arranged in a thin film form. This structure is often fabricated through techniques such as physical vapor deposition or chemical vapor deposition, where each layer is precisely deposited onto a substrate.
The term "layered" indicates that these thin films consist of two or more distinct layers, differing in composition or magnetic properties. Each layer within the structure typically has a unique combination of magnetic elements, allowing for tailored magnetic properties within the overall film. These layers can include ferromagnetic materials, antiferromagnetic materials, or combinations of both, depending on the desired properties of the film.
The primary purpose of creating layered magnetic thin films is to manipulate and control magnetic behavior for a range of scientific and technological applications. By altering the composition, thickness, and arrangement of the layers, researchers can achieve specific magnetic properties such as tunable magnetic anisotropy, enhanced magneto-optical properties, and improved magnetic stability.
Layered magnetic thin films find applications in various fields, including magnetic storage devices (e.g., hard drives), spintronics, sensors, and magnetic recording media. The ability to finely tune the magnetic properties of these films enables advancements in information storage densities, energy-efficient electronics, and magnetic sensing technology.
