Study of Structural and Magnetic Properties of Antiferromagnetic Cr <sub>2</sub> MnGe Heusler Alloy
Engineered Heusler alloys have potential applications in spintronic devices owing to their fascinating properties. Therefore, we synthesized a ternary Cr2MnGe Heusler alloy using a simple solid-state reaction. Rietveld refinement of the X-ray Diffraction data confirmed the presence of a cubic Fd-3m structure, specifically the B32a disorder Heusler phase with a space group number of 227. The microstructure and chemical composition of the Cr2MnGe sample confirmed agglomeration and adherence to the nominal composition of the Heusler alloy. Furthermore, the Cr2MnGe sample exhibits antiferromagnetic behavior with ferromagnetic clusters due to the site swapping of Cr-Mn and Cr-Ge, which contributes to a magnetic signal in the zero-fieldcooled and field-cooled measurements. These findings highlight the potential of Cr<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub>MnGe for application in magnetic tunnel junctions and spin valves, contributing to advancements in spintronic technologies.
