Nanoscale multifunctional magnetic materials show unique size, shape, and structure dependent magnetic properties, making them suitable for a range of biomedical applications from magnetic hyperthermia therapy to magnetic actuation, magnetic drug delivery, and magnetic resonance imaging (MRI). The development of ultra-high performance magnetic nanoparticles faces a critical challenge related to the transition from ferromagnetism (multidomain structure) to superparamagnetism (single domain) as the size of materials approaches to the nanoscale. This has become a physical limit to the use of magnetic nanoparticles for practical applications. To address this, I will first discuss recently provisionally patented manufacturing technology to develop ultra-high performance magnetic materials of superior magnetic properties (i.e. the realization of ferromagnetic behavior at the nanoscale). In the second part, I will talk about a simple self-assembly based strategy for designing artificial materials via the assembly of nanoparticles of different sizes and materials and their collective magnetic and mechanical properties. Also, how magnetic interactions within self-assembled micro-and mesoscale materials contribute to the mechanical properties of the self-assembled magnetic materials which have not been explored yet, will be discussed. Understanding the collective properties of self-assembled materials is essential for fabricating intelligent magnetic materials with superior magnetic and mechanical properties for various practical applications from biomedical to energy and informationsolar cells in Apollo Power.
