Magnetic applications are ubiquitous in modern technology, yet the available materials are relatively limited in number and tunability. Bottom-up design is therefore appealing as it offers the possibility of atomic-level understanding and customization. Magnetic properties, however, often translate poorly between atomic, molecular, nano, and bulk scales. In this seminar, I will discuss our efforts to design magnetic systems with well-defined, robust magnetic parameters that translate across different size scales. Part one will focus on designing molecules that efficiently preserve single-ion anisotropy in the presence of the crystal field perturbations that are necessary to expand their dimensionality. The second part will focus on the implementation of ferrite nanoparticle composites as highly tunable magnetoresistive materials.
