Enabling atomic resolution in convergent beam EMCD measurements by the use of patterned apertures
Hasan Ali, Devendra Negi, Tobias Warnatz +3
We give an experimental demonstration of two types of recently proposed ventilator apertures which can be used to acquire electron magnetic circular dichroic (EMCD) signals in zone…

Proposal for measuring magnetism with patterned apertures
Devendra Negi, Jakob Spiegelberg, Shunsuke Muto +5
We propose a magnetic measurement method utilizing a patterned post-sample aperture in a transmission electron microscope. While utilizing electron magnetic circular dichroism, the…

Proposal for a three-dimensional magnetic measurement method with nanometer-scale depth resolution
Devendra Negi, Lewys Jones, Juan-Carlos Idrobo +1
We propose a magnetic measurement method based on combining depth sectioning and electron magnetic circular dichroism in scanning transmission electron microscopy. Electron vortex…
