Abstract

Perpendicular magnetic anisotropy (PMA) exhibited at ferromagnet/insulator interfaces plays a pivotal role in various spintronic devices such as magnetic recording and sensing applications. Recently, there has been a surge of interest in perpendicular magnetic tunnel junctions (p-MTJs) due to their remarkable stability and energy efficiency. Heusler alloys, a versatile family of compounds, have shown great promise in the development of p-MTJs. However, the selection of suitable Heusler ferromagnets and insulators with the desired interfacial properties presents a significant challenge. In this presentation, we will delve into our recent advancements in the quest for candidate Heusler/MgO material interfaces that exhibit robust PMA and possess other essential material characteristics crucial for the advancement of spintronic technologies. Our approach employs a high-throughput screening methodology to efficiently identify optimal material combinations, paving the way for enhanced performance and functionality in spintronic applications.
