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 the exploration of magnetism in these systems. I will present magnetization and thermodynamic measurements that indicate precise control of this introduced magnetic order in iron intercalated NbS2, with antiferromagnetic order being established at iron intercalation values above x = 1/3 in FexNbS2. In addition, I will discuss evidence of a new frustrated magnetic order emerging below critical intercalation values.
