Magnon spectroscopy in the electron microscope.

ABSTRACT: The miniaturization of transistors is approaching its limits owing to challenges in heat management and information transfer speed¹. To overcome these obstacles, emerging technologies such as spintronics² are being developed, which make use of the electron's spin as well as its charge. Local phenomena at interfaces or structural defects will greatly influence the efficiency of spin-based devices, making the ability to study spin-wave propagation at the nanoscale and atomic scale a key challenge^3,4. The development of high-spatial-resolution tools to investigate spin waves, also called magnons, at relevant length scales is thus essential to understand how their properties are affected by local features. Here we detect bulk THz magnons at the nanoscale using
