Tuning Magnetic Order with Iron Intercalation in Transition Metal Dichalcogenides

ORAL

Abstract

The transition metal dichalcogenides are a class of two-dimensional materials currently under intense research due to their attractive electronic properties. Through the process of intercalation, magnetic atoms can be inserted between the layers of these materials to introduce long range magnetic order, enabling exploration of magnetism in these systems. I will present magnetization and thermodynamic measurements that indicate antiferromagnetic order in iron intercalated NbS2. Crucially, we can use intercalation to control the strength of an emergent spin glass state below intercalation values of x = 1/3 in FexNbS2. The cooperation between this glassy phase and the antiferromagnetic order allow for the generation of substantial bias fields in the system.
