A substrate having a magnetic material thin film layer including a paramagnetic material between spaced ferromagnetic grain boundaries and a method of manufacturing the same

摘要

The present invention relates to a substrate on which a magnetic material thin film layer including a paramagnetic material is formed between spaced ferromagnetic grain boundaries, and a method of manufacturing the same. More specifically, the present invention is a substrate on which a metal oxide buffer layer is formed; And a magnetic material thin film layer formed on the buffer layer, wherein the magnetic material thin film layer is formed by depositing a ferromagnetic material on the buffer layer, and the metal hydroxide generated in the metal oxide buffer layer is removed to determine the ferromagnetic material. Comprising a ferromagnetic layer in which grain boundaries are formed to be spaced apart from each other, and a paramagnetic layer in which a paramagnetic material is deposited on top of the ferromagnetic layer and diffusely penetrated between the grain boundaries of the ferromagnetic layer formed to be spaced apart Disclosed is a substrate in which a magnetic material thin film layer including a paramagnetic material is formed between grain boundaries.
