Single scan STEM-EMCD in 3-beam orientation using a quadruple aperture
Hasan Ali, Sharath Kumar Manjeshwar Sathyanath, Cheuk-Wai Tai +5
The need to acquire multiple angle-resolved electron energy loss spectra (EELS) is one of the several critical challenges associated with electron magnetic circular dichroism (EMCD…

Simultaneous mapping of EMCD signals and crystal orientations in a transmission electron microscope
Hasan Ali, Jan Rusz, Tobias Warnatz +2
When magnetic properties are analysed in a TEM using the technique of electron magnetic circular dichroism (EMCD), one of the critical parameters is the sample orientation, and thi…

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…
