The role of heat assisted magnetic recording in future hard disk drive applications
… fast growing market for ultrahigh areal density HAMR-based HDDs. HAMR-based HDD for portable applications could very well be a disruptive technology in the magnetic recording industry. Companies that intend to profit from this technology need to invest on its development and must try to be …

Residual Model Learning for Microrobot Control
… a model of the Harvard Ambulatory MicroRobot (HAMR) using just 12 seconds of passively collected interaction data. The learned model is accurate enough to be leveraged as “proxy-simulator” for learning walking and turning behaviors using model-free reinforcement learning algorithms. RML …

Micromagnetic Study of Composite Media for High Density Heat Assisted Magnetic Recording
… like Heat Assisted Magnetic Recording (HAMR) are needed. On the other hand, the Solid State Drive (SSD) has developed quickly as another candidate for high density and high speed information media which makes this situation urgent. In this thesis, micromagnetic simulations of HAMR media …

Mapping plasmon excitations in gold nanostructures using electron energy loss spectroscopy
… their use in heat-assisted magnetic recording (HAMR) as a nanoscale heat source. This work begins by examining and comparing the plasmonic properties of what we call ’nanoraindrop‘ and ’nanolollipop‘ geometries, describing the advantages and disadvantages of each. We then review an annular …

Effects of AG on structural and magnetic properties of FePt thin films
… promising candidate for heat sink layer in FePt HAMR system because of its close lattice mismatch with FePt and good thermal conductivity.

Autonomous hierarchical adaptive mesh refinement for multiscale simulations
… the Hierarchical Adaptive Mesh Refinement (HAMR) system provides support not only for AMR, but also for autonomous data management, thereby decoupling the numerical techniques of a simulation from the adaptive grid hierarchy to which it is applied.

High Anisotropy Magnetic Materials for Data Storage and Spintronic Memory
… understanding of: development of FePt for HAMR media, effect of strain assisted switching on the spin state of FePt, and development of novel high anisotropy Mn-based materials with low magnetization. Finally, I will present my experimental realization of Ru as the 4th room temperature …
