Magnetic behavior in Vapor-Deposited Amorphous Thin Mn<sub>x</sub>Ge<sub>1-x </sub>Films

ORAL

Abstract

Crystalline manganese germanide (Mn-Ge) exhibits complex magnetic behavior, with the crystalline B20 phase being particularly notable for hosting helimagnetic order and skyrmion lattices. These non-collinear spin textures are sensitive to changes in temperature, magnetic field, and composition, making Mn-Ge alloys an attractive material for potential spintronic applications.

In order to explore the effects of disorder on its magnetic properties, we will report our progress growing amorphous MnxGe1-x thin films via physical vapor deposition and discuss the use of high-resolution transmission electron microscopy (HRTEM) to confirm the amorphous nature of the films. We will also highlight SQUID magnetometry measurements to examine the temperature- and field-dependent magnetization and compare with crystalline MnxGe1-x. Lastly, the measured properties will be compared with those of amorphous FexGe1-x and CoxGe1-x.
