Development of a scanning electron microscopy with polarization analysis system for magnetic imaging with ns time resolution and phase-sensitive dete…

2018

Scanning electron microscopy with polarization analysis is a powerful lab-based magnetic imaging technique offering simultaneous imaging of multiple magnetization components and a very high spatial resolution. However, one drawback of the technique is the long required acquisition time resulting from the low inherent efficiency of spin detection, which has limited the applicability of the technique to certain quasi-static measurement schemes and materials with high magnetic contrast. Here we demonstrate the ability to improve the signal-to-noise ratio for particular classes of measurements involving periodic excitation of the magnetic structure via the implementation of a digital phase-sens…

Optimalization of doubletone polarography

1977

Abstract Through the application of coherent fundamental frequencies, the synchronization of measuring frequency and dropping frequency, which facilitate the use of phase sensitive techniques, doubletone polarography could be developed into a highly sensitive polarographic method with a high resolution in common with all derivative methods.
