Keywords:
Magnetic materials, Data storage, Nanotechnology, Magnetic anisotropy, SpintronicsAbstract
Magnetic properties of advanced materials play a critical role in the development of modern data storage technologies, enabling high-density, energy-efficient, and high-speed information processing. This paper examines the fundamental magnetic characteristics—such as anisotropy, coercivity, and magnetization—of emerging materials including nanostructured systems, rare-earth alloys, Heusler compounds, and two-dimensional magnetic materials. It further explores their integration into advanced storage technologies such as perpendicular magnetic recording, heat-assisted magnetic recording, and spintronics-based devices like magnetic random-access memory. Special emphasis is placed on phenomena such as giant magnetoresistance, tunnel magnetoresistance, and spin-transfer torque, which underpin next-generation memory devices. The study also addresses key challenges including thermal stability, scalability, and the superparamagnetic limit. Overall, the paper highlights how tailoring magnetic properties at the nanoscale is essential for advancing data storage technologies and meeting the increasing global demand for efficient digital data management.
