What are the Key Properties of Magnetic Nanostructures?
Magnetic nanostructures exhibit unique properties such as: - Superparamagnetism: A phenomenon where nanoparticles become magnetized only in the presence of an external magnetic field and lose their magnetization when the field is removed. - Magnetic anisotropy: The directional dependence of a material's magnetic properties, which can be engineered for specific applications. - Exchange bias: An effect observed in nanostructures comprising ferromagnetic and antiferromagnetic layers, leading to enhanced stability of magnetic states.
