Magnetic heterostructures are materials composed of two or more layers with different magnetic properties. These layers can be made from various materials, such as metals or semiconductors, and are engineered to enhance specific magnetic behaviors. The interaction between the layers can lead to unique phenomena, such as increased magnetic stability or tunable magnetic properties. These structures are important in the field of spintronics, which utilizes the intrinsic spin of electrons for information processing. By manipulating the magnetic properties at the nanoscale, researchers aim to develop more efficient devices, including magnetic sensors and data storage technologies.
