Experimental observations of a topological spin singularity, the Bloch point in a patterned nanodisk

Abstract

Magnetic materials are representative functional systems serving as key ingredients in a variety of current applications, spanning from data storage and computing technologies to electric power generation and conversion. To fully exploit such materials in current and next generation applications, including spintronic-based ultra-low power computing, as well as expanding the portfolio of earth-abundant high-energy product magnetic materials, we need to gain a comprehensive understanding of functional order, topology, and dynamics on the nanoscale in magnetic materials. Soft X-ray magnetic dichroism tools in concert with lab-based structural and magnetic characterization offer a multidimensional approach to understand the complex interactions underlying long range magnetic order, functional properties, and dynamic behavior relevant to topology in these systems. This workshop will explore current and future research in these fields taking place at the Advanced Light Source, and emphasize contributions from early career scientists such as students and postdocs as well as overview talks from established experts in the field. Participants are also invited to join a 'data town hall' on the afternoon of the last day where we will discuss current and future needs and directions for data analysis and data management for magnetic spectroscopy and imaging.
