SEMPA Imaging for Spintronics Applications



John Unguris, Daniel T. Pierce, Seok-Hwan Chung


Scanning Electron Microscopy with Polarization Analysis (SEMPA) provides high resolution (10 nm) magnetization images simultaneously with, but independent of, the topography. Such information is very useful in studying spintronics devices as illustrated by three examples: 1) exchange coupling of magnetic layers, 2) spin-transfer switching in magnetic nanowires, and 3) the ferromagnetic metal-semiconductor interface.
