The development of a table-top system to study the spatio-temporal dynamics of magnetic devices on fundamental scales to magnetism is of particular importance to engineering high performance spintronic memory and logic devices that are simultaneously high-speed, high-density, low-power, and radiation hard. Although facility-based measurements at the scale of 50 nm and 100 ps are available using coherent synchotron sources like the Advanced Light Source in Berkeley, a table topic system would enable high-throughput studies to develop the science and technology to support such high-performance spintronics. In this project we studied approaches to exceeding the diffraction limit for optical magnetic microscopy while still retaining the excellent temporal resolution that is accessible with pulsed lasers.
