Super-resolution magnetic correlation microscope

Ziel

Over the past several decades, the microelectronics industry has revolutionized nearly every aspect of our lives. The ever-growing need for faster and more efficient devices, recently emphasized by the extreme computing requirements of artificial intelligence techniques, is pushing traditional device architectures to their limits, prompting the search for novel physical realization of such devices. Currently, the most promising approach involves magnetic materials, as can be witnessed through the recent advent of magnetic memories as well as development of logic devices based on hybrid electronic/magnetic structures and the flow of magnetic charge, referred to as “spintronics”.

Despite the tremendous progress achieved, the field of spintronics is held back by both fundamental and practical open questions related to issues such as magnetization switching and excitation dynamics, effects of magnetic and topological defects, and local conductance properties of magnetic devices. A major obstacle encountered in addressing these important open questions stems from limited measurement and characterization techniques – high-resolution sensing of dynamic response and conductance cannot be achieved with existing near-field tools.

I propose a new kind of microscope: a far-field super-resolution magnetic correlation microscopy platform. Building upon progress in the field of magnetic microscopy using defects in diamond, including our recent results studying chiral-magnetic hybrid devices, this unique platform will constitute a leap forward over state-of-the-art magnetic sensing techniques. It will enable for the first time local nanometer scale magnetic correlation data unattainable by other means. I will employ these ground-breaking capabilities to reveal the dynamics related to excitation creation and control in 2D magnetic materials and current/spin conductance, leading to breakthrough magnetic device architectures.
