Fusion AX: Amp Up Your Devices

Probing Magnetic Properties at the Nanoscale: In Situ Hall Measurements in a TEM

Coming Tuesday, the 10th of December, we will have the next installment of our webinar series surrounding electronic devices with Fusion AX! Don't forget to sign up! This webinar will be presented by Dr. Darius Pohl:

Magnetic domains and non-trivial textures such as skyrmions are often characterized using anomalous Hall effect measurements and Lorentz TEM (LTEM) imaging. However, these techniques are typically applied to separate samples, making it difficult to directly correlate transport and imaging data. To address this problem, we have developed an advanced in-situ magneto-transport setup within a transmission electron microscope that allows simultaneous magnetic imaging and four-probe electrical measurements on the same sample.

In this webinar, he will give insights into our new setup and describe our proof-of-concept experiment on a thin Ni film, where we imaged magnetic domain patterns while performing in-situ Hall effect measurements. Further experiments on a lamella of Mn1.4PtSn provide insights into the magnetic signatures of anti-skyrmions. These results demonstrate the feasibility of combining high-resolution magnetic imaging and Hall measurements in the TEM using biasing holders.

The third webinar in this series will take place in the 9th of January, by Dr. Xiangli Zhong who will talk about FIB Preparations for In Situ TEM Analysis
