Electron has two kinds of intrinsic properties, “charge”and “spin.” In the past century, the charge-based electronics had achieved a great success in utilization and control of electron charge. Since 1980s, a research field called spintronics, in which people utilize the electron spin instead of charge to carry information, has emerged. The goal of spintronics is to understand fundamental physics of electron spin and develop solid-state devices combining conventional charge-based microelectronics with spin-dependent effects. Many scientists believe that the 21st century will be a “Century of Spin.” Nanomaterials and Nanotechnologies have provided historical opportunities for research and development of novel spintronics materials and devices. Nanostructured magnetic materials manifest fascinating properties compared to the bulks because of size effect and quantum effect. Nanotechnologies have been proven to be an effective way to fabricate devices with fine nanostructures. The combination of spintronics and nanomaterials will undisputedly open new pathways in solid state physics.

Nanostructured magnetic materials have received intensive interest in scientific and industrial areas for their novel or crossover properties, which introduce new physics and high potential for technical applications. Research on their fundamental electronic and magnetic properties as well as coupling states is the base of high-performance materials development and devices design. This special issue focuses on fabrication and fundamental physical properties of nanostructured magnetic materials for spintronics application. It will become an important international medium for researchers to summarize their most recent progresses and to exchange ideas in the field. Potential topics include, but are not limited to:

• Magnetic ultrathin films
• Magnetic multilayer films
• Magnetic pattern structures
• Magnetic nanoparticles
• One-dimensional nanostructured magnetic materials (nanotubes, nanowires, nanorods, etc.)
• Nanoscale ferromagnetic semiconductors
• Nanoscale multiferroic materials
• Rare-earth-related nanostructured magnetic materials
